Characterization of the exopolygalacturonate lyase PelX of Erwinia chrysanthemi 3937. (1/703)

Erwinia chrysanthemi 3937 secretes several pectinolytic enzymes, among which eight isoenzymes of pectate lyases with an endo-cleaving mode (PelA, PelB, PelC, PelD, PelE, PelI, PelL, and PelZ) have been identified. Two exo-cleaving enzymes, the exopolygalacturonate lyase, PelX, and an exo-poly-alpha-D-galacturonosidase, PehX, have been previously identified in other E. chrysanthemi strains. Using a genomic bank of a 3937 mutant with the major pel genes deleted, we cloned a pectinase gene identified as pelX, encoding the exopolygalacturonate lyase. The deduced amino acid sequence of the 3937 PelX is very similar to the PelX of another E. chrysanthemi strain, EC16, except in the 43 C-terminal amino acids. PelX also has homology to the endo-pectate lyase PelL of E. chrysanthemi but has a N-terminal extension of 324 residues. The transcription of pelX, analyzed by gene fusions, is dependent on several environmental conditions. It is induced by pectic catabolic products and affected by growth phase, oxygen limitation, nitrogen starvation, and catabolite repression. Regulation of pelX expression is dependent on the KdgR repressor, which controls almost all the steps of pectin catabolism, and on the global activator of sugar catabolism, cyclic AMP receptor protein. In contrast, PecS and PecT, two repressors of the transcription of most pectate lyase genes, are not involved in pelX expression. The pelX mutant displayed reduced pathogenicity on chicory leaves, but its virulence on potato tubers or Saintpaulia ionantha plants did not appear to be affected. The purified PelX protein has no maceration activity on plant tissues. Tetragalacturonate is the best substrate of PelX, but PelX also has good activity on longer oligomers. Therefore, the estimated number of binding subsites for PelX is 4, extending from subsites -2 to +2. PelX and PehX were shown to be localized in the periplasm of E. chrysanthemi 3937. PelX catalyzed the formation of unsaturated digalacturonates by attack from the reducing end of the substrate, while PehX released digalacturonates by attack from the nonreducing end of the substrate. Thus, the two types of exo-degrading enzymes appeared complementary in the degradation of pectic polymers, since they act on both extremities of the polymeric chain.  (+info)

Dietary pectin lowers sphingomyelin concentration in VLDL and raises hepatic sphingomyelinase activity in rats. (2/703)

There is evidence that cholesterol and sphingomyelin metabolism are interrelated, and thus the hypothesis tested was that dietary pectin, because it can alter hepatic cholesterol metabolism, would also alter hepatic sphingomyelin metabolism. For that purpose, 4-wk-old female Wistar rats were fed a diet without or with pectin (20 g/100 g) up to 21 d. In accordance with previous work, pectin consumption caused a significant (P < 0.001) reduction in hepatic (65%), whole plasma (37%), and VLDL (80%) cholesterol levels. Pectin also significantly reduced VLDL sphingomyelin concentrations (57%), but raised the amount of sphingomyelin in the high density lipoproteins (HDL)-2 fractions (58%), so that the level of sphingomyelin in whole plasma remained unaffected. Pectin did not affect the sphingomyelin concentration in the liver. Pectin consumption did not affect the hepatic sphingomyelin synthesizing enzymes, serine palmitoyltransferase, phosphatidylcholine:ceramide phosphocholine transferase, or phosphatidylethanolamine:ceramide phosphoethanolamine transferase. In contrast, dietary pectin activated both lysosomal (28%) and plasma membrane (26%) sphingomyelinase and thus may have enhanced sphingomyelin degradation. An attempt was made to describe the effects of dietary pectin on sphingomyelin metabolism in terms of altered fluxes through liver and plasma, with whole liver and whole plasma concentrations of sphingomyelin remaining unaffected.  (+info)

Kinetic characterization of Aspergillus niger N400 endopolygalacturonases I, II and C. (3/703)

Endopolygalacturonases I, II and C isolated from recombinant Aspergillus niger strains were characterized with respect to pH optimum, activity on polygalacturonic acid and mode of action and kinetics on oligogalacturonates of different chain length (n = 3-7). Apparent Vmax values using polygalacturonate as a substrate at the pH optimum, pH 4.1, were calculated as 13.8 mukat.mg-1, 36.5 mukat.mg-1 and 415 nkat.mg-1 for endopolygalacturonases I, II and C, respectively. K(m) values were < 0.15 mg.mL-1 for all three enzymes. Product progression analysis using polygalacturonate as a substrate revealed a random cleavage pattern for all three enzymes and suggested processive behavior for endopolygalacturonases I and C. This result was confirmed by analysis of the mode of action using oligogalacturonates. Processivity was observed when the degree of polymerization of the substrate exceeded 5 or 6 for endopolygalacturonase I and endopolygalacturonase C, respectively. The bond-cleavage frequencies obtained for the hydrolysis of the oligogalacturonates were used to assess subsite maps. The maps indicate that the minimum number of subsites is seven for all three enzymes. Using pectins of various degrees of esterification, it was shown that endopolygalacturonase II is the most sensitive to the presence of methyl esters. Like endopolygalacturonase II, endopolygalacturonases I, C and E, which was also included in this part of the study, preferred the non-esterified pectate. Additional differences in substrate specificity were revealed by analysis of the reaction products of hydrolysis of a mixture of pectate lyase-generated delta 4,5-unsaturated oligogalacturonates of degree of polymerization 4-8. Whereas endopolygalacturonase I showed a strong preference for generating the delta 4,5-unsaturated dimer, with endopolygalacturonase II the delta 4,5-unsaturated trimer accumulated, indicating further differences in substrate specificity. For endopolygalacturonases C and E both the delta 4,5-unsaturated dimer and trimer were observed, although in different ratios.  (+info)

Cloning and partial characterization of endopolygalacturonase genes from Botrytis cinerea. (4/703)

Botrytis cinerea is a plant-pathogenic fungus infecting over 200 different plant species. We use a molecular genetic approach to study the process of pectin degradation by the fungus. Recently, we described the cloning and characterization of an endopolygalacturonase (endoPG) gene from B. cinerea (Bcpg1) which is required for full virulence. Here we describe the cloning and characterization of five additional endoPG-encoding genes from B. cinerea SAS56. The identity at the amino acid level between the six endoPGs of B. cinerea varied from 34 to 73%. Phylogenetic analysis, by using a group of 35 related fungal endoPGs and as an outgroup one plant PG, resulted in the identification of five monophyletic groups of closely related proteins. The endoPG proteins from B. cinerea SAS56 could be assigned to three different monophyletic groups. DNA blot analysis revealed the presence of the complete endoPG gene family in other strains of B. cinerea, as well as in other Botrytis species. Differential gene expression of the gene family members was found in mycelium grown in liquid culture with either glucose or polygalacturonic acid as the carbon source.  (+info)

Azospirillum irakense produces a novel type of pectate lyase. (5/703)

The pelA gene from the N2-fixing plant-associated bacterium Azospirillum irakense, encoding a pectate lyase, was isolated by heterologous expression in Escherichia coli. Nucleotide sequence analysis of the region containing pelA indicated an open reading frame of 1,296 bp, coding for a preprotein of 432 amino acids with a typical amino-terminal signal peptide of 24 amino acids. N-terminal amino acid sequencing confirmed the processing of the protein in E. coli at the signal peptidase cleavage site predicted by nucleotide sequence analysis. Analysis of the amino acid sequence of PelA revealed no homology to other known pectinases, indicating that PelA belongs to a new pectate lyase family. PelA macerates potato tuber tissue, has an alkaline pH optimum, and requires Ca2+ for its activity. Of several divalent cations tested, none could substitute for Ca2+. Methyl-esterified pectin (with a degree of esterification up to 93%) and polygalacturonate can be used as substrates. Characterization of the degradation products formed upon incubation with polygalacturonate indicated that PelA is an endo-pectate lyase generating unsaturated digalacturonide as the major end product. Regulation of pelA expression was studied by means of a translational pelA-gusA fusion. Transcription of this fusion is low under all growth conditions tested and is dependent on the growth phase. In addition, pelA expression was found to be induced by pectin. An A. irakense pelA::Tn5 mutant still displayed pectate lyase activity, suggesting the presence of multiple pectate lyase genes in A. irakense.  (+info)

Potential of short chain fatty acids to modulate the induction of DNA damage and changes in the intracellular calcium concentration by oxidative stress in isolated rat distal colon cells. (6/703)

Short chain fatty acids (SCFA) are considered to be beneficial fermentation products in the gut by exerting trophic effects in non-transformed colon cells and by slowing proliferation and enhancing differentiation in colonic tumour cells. We have studied the further effects of SCFA on cellular events of early carcinogenesis, genotoxicity and cytotoxicity in rat distal colon cells. Cytotoxicity was assessed by measuring trypan blue exclusion and by determining the H2O2-induced changes in intracellular calcium concentration ([Ca2+]i) using a fluorospectrophotometer and the calcium-sensitive fluorescent dye Fura-2. The microgel electrophoresis technique (COMET assay) was used to assess oxidative DNA damage. Individual SCFA and physiological SCFA mixtures were investigated for their potential to prevent DNA and cell damage induced by H2O2. For this, freshly isolated colon cells were treated with H2O2 (100-500 microM) and 6.25 mM SCFA. We have found 100-500 microM H2O2 to cause a fast initial increase in [Ca2+]i, whereafter the levels gradually further increased. Addition of SCFA did not affect [Ca2+]i nor did it reduce the H2O2-induced increase in [Ca2+]i. Butyrate and acetate were able to reduce the induction of DNA damage by 100, 200 and 500 microM H2O2, respectively. In contrast, i-butyrate and propionate were ineffective. The degree of reduction of DNA damage for the two protective SCFA was similar. Physiological mixtures containing acetate, propionate and butyrate in ratios of 41:21:38 or 75:15:10 that are expected to arise in the colon after fermentation of resistant starches and pectin, respectively, did not show significant antigenotoxic effects. The major difference between butyrate and acetate, on one hand, and i-butyrate and propionate, on the other hand, is that the former compounds are utilized best as energy sources by the colon cells. Therefore, our results on antigenotoxicity coupled with the findings on [Ca2+]i homeostasis indicate that molecular effects on the energy system render these non-transformed, freshly isolated colon cells to be less susceptible to H2O2.  (+info)

The plant cell wall polysaccharide rhamnogalacturonan II self-assembles into a covalently cross-linked dimer. (7/703)

The location of the 1:2 borate-diol ester cross-link in the dimer of the plant cell wall polysaccharide rhamnogalacturonan II (RG-II) has been determined. The ester cross-links the apiofuranosyl residue of the 2-O-methyl-D-xylose-containing side chains in each of the subunits of the dimer. The apiofuranosyl residue in each of the two aceric acid-containing side chains is not esterified. The site of borate esterification is identical in naturally occurring and in in vitro synthesized dimer. Pb2+, La3+, and Ca2+ increase dimer formation in vitro in a concentration- and pH-dependent manner. Pb2+ is the most effective cation. The dimer accounts for 55% of the RG-II when the monomer (0.5 mM) is treated for 5 min at pH 3.5 with boric acid (1 mM) and Pb2+ (0.5 mM); at pH 5 the rate of conversion is somewhat slower. Hg2+ does not increase the rate of dimer formation. A cation's charge density and its ability to form a coordination complex with RG-II, in addition to steric factors, may regulate the rate and stability of dimer formation in vitro. Our data provide evidence that the structure of RG-II itself determines which apiofuranosyl residues are esterified with borate and that in the presence of boric acid and certain cations, two RG-II monomers self-assemble to form a dimer.  (+info)

Multiple epoxide hydrolases in Alternaria alternata f. sp. lycopersici and their relationship to medium composition and host-specific toxin production. (8/703)

The production of Alternaria alternata f. sp. lycopersici host-specific toxins (AAL toxins) and epoxide hydrolase (EH) activity were studied during the growth of this plant-pathogenic fungus in stationary liquid cultures. Media containing pectin as the primary carbon source displayed peaks of EH activity at day 4 and at day 12. When pectin was replaced by glucose, there was a single peak of EH activity at day 6. Partial characterization of the EH activities suggests the presence of three biochemically distinguishable EH activities. Two of them have a molecular mass of 25 kDa and a pI of 4.9, while the other has a molecular mass of 20 kDa and a pI of 4.7. Each of the EH activities can be distinguished by substrate preference and sensitivity to inhibitors. The EH activities present at day 6 (glucose) or day 12 (pectin) are concomitant with AAL toxin production.  (+info)

Control and hyperhydric micropropagated plantlets from three carnation cultivars have been used to study their pectin composition and the activity of pectin methyl esterases (PMEs; EC 3.1.1.11). Pectins are a highly heterogeneous group of polymers that contribute to cell adhesion, cell wall architecture, and cell wall mechanical strength. Pectins control cell wall porosity and cell wall ionic status and are implicated in intercellular space development. The degree of esterification of pectins is controlled by the activity of cell wall PMEs; their different actions can affect the properties of the cell wall, which have been considered important with respect to controlling the development of hyperhydricity. The total pectins of hyperhydric leaves of the three varieties were significantly reduced in comparison with controls. The pectate fraction was significantly increased in hyperhydric leaves of all varieties while soluble pectins and protopectins were significantly lower. The PME activity of ...

Eukaryotic cells perform continuous recycling of the plasma membrane proteins and extracellular matrix molecules from the cell surface back to the cytoplasm (for plant cells, see Low and Chandra, 1994; Robinson et al., 1998). Our recent study (Baluška et al., 2002) provides experimental evidence that cell wall pectins are internalized after in muro de-esterification (Micheli, 2001) and cross-linking with calcium and boron (Matoh and Kobayashi, 1998;Kobayashi et al., 1999). These almost exclusive cell wall pectin epitopes, reactive to JIM5 and RGII antibodies, accumulate abundantly within intracellular BFA-induced compartments, which are obviously formed through aggregation of trans-Golgi networks and putative plant endosomes (Baluška et al., 2002). Here, we report that intracellular BFA compartments accumulate these cell wall pectins in meristematic cells of maize and wheat, but not of zucchini and alfalfa, root apices. Intriguingly, boron deprivation inhibits endocytosis of cell wall pectins. ...
Pectin is also known to contain other neutral sugars which are present in side chains. The most common side chain sugars are xylose, galactose and arabinose. The sidechains tend to occur in groups and have led to the description of the pectin molecule as having hairy and smooth regions.. Commercially pectins are categorised according to their methoxy content and wether they from gels quickly or slowly. Roughly speaking pectins can be split in to high methoxy pectins (,50% esterified) and low methoxy pectins (,50%esterified). Low methoxy pectins can also be amidated or not. ...

HM pectins have the ability to form gels with sugar and acid, so-called low water activity gels or sugar-acid-pectin gels. Such a gel is considered a 2-dimensional network of pectin molecules in which the solvent (water) with the co-solutes sugar and acid are immobilised. This results in a system resisting deformation and showing a stress-strain relationship for small deformation. The build up of the 3-d network is based on the formation of junction zones in which there are chain associations stabilised by hydrogen bonding between undissociated carboxyl and secondary alcohol groups and by hydrophobic interaction between methyl esters.. The gelation mechanism of pectins is mainly governed by their degree of esterification (DE). For the low methoxyl pectins, denoted LMP (DE , 50%), gelation results from specific non-covalent ionic interactions between blocks of galacturonic acid residues of the pectin backbone and with divalent ions such as calcium. The affinity of pectin chains towards calcium is ...

While establishing a nitrogen-fixing symbiosis with leguminous plants, rhizobia are faced with the problem of penetrating the plant cell wall at several stages of the infection process. One of the major components of this barrier is pectin, a heteropolysaccharide composed mainly of galacturonic acid subunits. So far, no enzymes capable of degrading pectin have been isolated from rhizobia. Here, we make an inventory of rhizobial candidate pectinolytic enzymes based on available genome sequence data and present an initial biochemical and functional characterization of a protein selected from this list. Rhizobium etli hrpW is associated with genes encoding a type III secretion system, a macromolecular structure that allows bacteria to directly inject so-called effector proteins into a eukaryotic host's cell cytosol and an essential virulence determinant of many Gram-negative pathogenic bacteria. In contrast to harpin HrpW from phytopathogens, R. etli HrpW possesses pectate lyase activity and is most
One pilot study from 2008 on the role of modified citrus pectin as an effective chelator of lead in children hospitalized with toxic lead levels found a dramatic decrease in blood serum levels of lead(P = .0016; 161% average change) and a dramatic increase in 24-hour urine collection (P = .0007; 132% average change).. The study concluded -. The need for a gentle, safe heavy metal-chelating agent, especially for children with high environmental chronic exposure, is great. The dramatic results and no observed adverse effects in this pilot study along with previous reports of the safe and effective use of MCP in adults indicate that MCP could be such an agent. Further studies to confirm its benefits are justified. [1]. Five case studies from 2007 showed a significant reduction in toxic heavy metals (74% average decrease), which was achieved without side effects, with the use of PectaSol-C (modified citrus pectin) (MCP) (EcoNugenics; Santa Rosa, CA, USA) alone or with an MCP/alginates ...

Pectins are one of the main components of plant cell walls. They are secreted to the wall as highly methylesterified forms that can be de-esterified by pectin methylesterases (PMEs). The degree of methylesterification of pectins changes during development, PMEs are involved in the cell wall remodeling that occurs during diverse plant developmental processes. Nevertheless, the functional meaning of pectin-related wall remodeling in different cell types and processes remains unclear. In vivo, the microspore follows the gametophytic pathway and differentiates to form the pollen grain. In vitro, the microspore can be reprogrammed by stress treatments becoming a totipotent cell that starts to proliferate and follows the embryogenic pathway, a process known as microspore embryogenesis. To investigate if the change of developmental programme of the microspore towards embryogenesis involves changes in pectin esterification levels, which would cause the cell wall remodeling during the process, in the present

Although the viscosity of aqueous solution of high methoxyl pectin is known to increase drastically when sugars coexist, the detailed mechanism for the increase in viscosity was not fully understood. Therefore, the viscosity of citrus and apple pectin solutions with various sugars compositions was measured with temperature varying from 5 to 40°C to analyze the intermolecular interactions among pectin molecules. For single-composition pectin solutions, the activation energy for viscosity, ,I,E,SUB,a,/SUB,,/I,, increased from 17.5 to 31.9 kJ/mol with an increase in pectin concentration up to 2% for the case of citrus pectin, reflecting the increase in pectin-pectin interaction. For pectin solutions with coexisting sugars, ,I,E,SUB,a,/SUB,,/I, increased more with increasing sugar concentration. When compared at the same water activity, the increase in ,I,E,SUB,a,/SUB,,/I, is also dependent on the type of sugar. Sugars with stronger solvent-ordering activity produced greater increases in ...
The complex carbohydrates apple pectin, citrus pectin, flaxseed mucilage, blood group A substance, gum acacia, and gum myrrh as well as an extract of RBC, when examined in a pattern test, were shown to inhibit the agglutination of chicken RBC by influenza A virus. A number of other simple and complex carbohydrates showed no inhibitory effect. The hemagglutination-inhibiting action of apple pectin was examined in some detail and evidence was adduced to show that it affected both virus and red cell. Apple pectin was also found to inhibit the multiplication of influenza A virus in embryonated eggs.. ...
Most people know pectin as a common household gelling agent in making jams and jellies, but its uses are vast. It has anticancer properties, for instance, and may have a role in important biological functions including plant growth and development and defense against disease.. Despite the importance of pectin as a major component in the primary walls of plants, scientists have known relatively little about how this family of complex polysaccharides is made. Especially perplexing has been how the synthesis of the three different classes of pectic polysaccharides is coordinated to produce the pectin matrix in cell walls.. Now, in what has been described as a crucial breakthrough in pectin biosynthesis, a team of researchers at the University of Georgia has discovered a gene that encodes one of the proteins responsible for pectin synthesis. This is a powerful new molecular tool that could help researchers understand-and potentially manipulate-pectins.. The result, which arose from the use of ...
Sugar beet pectin was degraded enzymatically and separated by ion exchange chromatography into series of highly purified homogalacturonides and rhamnogalacturonides. MALDI-TOF/TOF mass-spectrometry was used to determine sizes and structural features. The methodology was based on the sequential use of monocomponent enzymes that were selected to target specific substructures in the sugar beet pectin. Notably pectin lyase and rhamnogalacturonan I lyase were used, which allowed detection of the resulting cleavage products by UV spectroscopy. Seven different homogalacturonides (HG) with degrees of polymerization (DP) from 2 to 8 and six different rhamnogalacturonide (RGI) structures, ranging from DP4 to 6 with defined galactose substitutions were purified. Total recoveries of 200 mg homogalacturonides and 67 mg rhamnogalacturonides per gram sugar beet pectin were obtained. This integrated biorefining method provides an option for advanced upgrading of sugar beet pectin into HG and RGI ...
Regarding NOT using sugar to make jelly or jam: the sugar in these recipes is REQUIRED for the chemical reaction of the pectin and the liquid in the fruit to form a gel.. Pectin is a naturally-occurring carbohydrate found in the peel of many fruits-pectin manufacturers simply extract the pectin from fruit (typically unripe apples), concentrate and dry it, and sell it for thickening jams and jellies.. There are only two types of real pectin (meaning that they are pectin only, without other additives): high-methoxyl pectin (regular pectin) and low-methoxyl pectin. (The methoxyl is a specific chemical group on the pectin molecule…). Regular pectin will ONLY work to form a gel when the EXACT amount of sugar and acid are present for a given amount of fruit-this is why pectin packages always state how much sugar and lemon juice to use for particular kinds of fruit.. Low-methoxyl pectin is chemically different (although similar to) from regular pectin because it requires a calcium solution, NOT ...
Niacin (Vitamin B3) is known to effectively and safely treat hypercholesterolemia. However, use of niacin is limited due to incidents of flushing which limits its acceptability. Some information suggests that applesauce can reduce the incidence and severity of flushing. The apple pectin in particular is thought to be the ingredient that affects this reaction. To determine if the apple pectin does affect flushing from niacin, the investigators will study the affects of isolated apple pectin in pill form. The investigators plan on recruiting 100 patients, and giving them 1000 mg of Niacin to induce flushing. Patients will be divided into 4 treatment groups and receive either pectin, aspirin, a combination of both, or placebo. Incidents and severity of flushing will be monitored for up to 6 hours post Niacin ingestion ...
Plant biomass is a potentially important renewable source of energy and industrial products. The natural recalcitrance of the cell walls to enzymatic degradation (saccharification), which plants have evolved to defend themselves from biotic stresses, represents a major bottleneck for the industrial bioconversion of lignocellulosic biomasses. The identification of factors that influence the cell wall recalcitrance to saccharification may help to overcome the existing limitations that hamper the utilization of biomass. Here we have investigated in Arabidopsis thaliana the impact of homogalacturonan (HG) content and structure on tissue saccharification. We characterized mutants affected in genes encoding proteins involved in HG biosynthesis (quasimodo2-1; qua2-1) and methylesterification (pectin methylesterase 3; pme3). We also analyzed the natural variation of Arabidopsis through the characterization of a nested core collection of 24 accessions generated to maximize genetic variability. We found a

Pectin is mainly D-galacturonic acid connected by α (1-4) glycosidic linkages. The side chains of pectin may contain small amounts of other sugars such as L-fructose, D-glucose, D-mannose, and D-xylose. In jams, pectin is what thickens the final product via cross-linking of the large polymer chains.[23] Freezer jam is uncooked (or cooked less than 5 minutes), then stored frozen. It is popular in parts of North America for its very fresh taste. Recipes without added pectin use the natural pectin in the fruit to set. Tart apples, sour blackberries, cranberries, currants, gooseberries, Concord grapes, soft plums, and quinces work well in recipes without added pectin.[24] Other fruits, such as apricots, blueberries, cherries, peaches, pineapple, raspberries, rhubarb, and strawberries are low in pectin. In order to set, or gel, they must be combined with one of the higher pectin fruits or used with commercially produced or homemade pectin.[25][26] Use of added pectin decreases cooking time. In ...

Diagnosed with multiple myeloma in 3/2011. Had radiation and chemo, and a stem cell transplant in Sept. 2011. In complete remission. WBC was in normal range (6.1) from Nov.2011 to Feb. 2012. Placed on 15 mgs. Revlimid maintenance, and in March 2011, WBC, started to decrease. Was then placed on 10 mgs. and in April, WBC decreased again. For two more months the dose was down to 5mgs. and the count went to 2.8, the first month, and 1.8 the next. Neutrophils were low so I was given a Neupogen shot, and off the 5 mgs.revlimid for two weeks. Just had another WBC taken and it went up to 2.2, and Absolute Neutrophil 800, Hgb 11.4, and plts. normal at 275,000. I was told to stay off the revlimid for another 2 weeks, and have another WBC then. If the WBC is still low then, a bone marrow biopsy will be done to determine why it continues to be low. Will the Mod. Citrus Pectin help increase the WBC? Is it safe with Revlimid? Thank You!. ...
Aims: To screen industrially important extracellular enzymes from the newly isolated alkalophilic bacilli and to characterize them by phenotypic and 16S-internal transcribed spacer (ITS) rDNA restriction pattern analysis. Methods and Results: Three different environmental samples, soil, leather and horse faeces, were collected within the province of Izmir. Isolates grown on Horikoshi-I medium for 24 h at 37°C were screened for extracellular enzyme activity by using eight different substrates: birchwood xylan, carboxymethylcellulose, casein, citrus pectin, polygalacturonic acid, soluble starch, and Tween 20 and 80. In total, 115 extracellular enzyme-producing bacilli were obtained. Casein was hydrolysed by 78%, soluble starch by 67%, citrus pectin by 63%, polygalacturonic acid by 62%, Tween 20 by 34%, birchwood xylan by 16%, Tween 80 by 12%, and carboxymethylcellulose by 3% of the isolates. The isolates were differentiated into 19 distinct homology groups by the 16S-ITS rDNA restriction pattern ...

R-lipoic acid also increases the level of the bodys premier intracellular antioxidant glutathione, in addition to having its own antioxidant activity in the body ...
|p|Amidated Low Methoxyl Pectin (e440ii) is a modified form of pectin extracted from the peels of citrus fruit. Pectin consists of a complex set of polysaccharides that are present in most primary cell walls of plants. The main use for pectin is as a gell
The galacturonic acid molecules form a smooth backbone. The other sugar molecules branch off this backbone to create what are known as pectins hairy regions.. Pectins molecules are long and easily entangle with each other. In foods and beverages, this property is very useful because it results in a thickening of the products texture and improved stability.. For more information, download our Factsheet: The Molecular Structure of Pectin. ...
Plant Wall Cell Structure. When pectin is extracted, much of the hairy regions are destroyed, leaving mainly the smooth galacturonic acid regions, with a few neutral sugar units attached or in the main linear chain. The nature and placing of these neutral sugars may vary with the source material, and have some influence on the properties of pectins from different origins. However, the biggest influence on pectin properties is the degree of esterification (DE), which determines, for example, the degree of reactivity with calcium and other cations.. ...
Citation: Luzio, G.A. 2004. Investigation of galacturonic acid colorimetric assay of pectin in citrus peel. Subtropical Technology Conference Proceedings. 55:42. Interpretive Summary: Technical Abstract: The amount of galacturonic acid residues in samples containing pectin is an important parameter in the quantitative and structural analysis of this complex carbohydrate. This presentation describes a method to determine the content of galacturonic acid in samples containing pectin such as citrus peel, using a glass microtiter plate and microtiter plate-reading equipment with standard interference filters. The assay is a modification of a procedure involving the hydrolysis of pectin in 80% sulfuric acid at 80°C followed by a coloring step with 3,5 dimethylphenol reagent at room temperature. The previous assay was difficult to apply routinely if large numbers of samples must be analyzed due to color changes that are time dependent, and that involve transferring of strongly acidic solutions to a ...
Auxin induces rapid gene expression changes throughout root development. How auxin-induced transcriptional responses relate to changes in protein abundance is not well characterized. This report identifies early auxin responsive proteins in roots at 30 min and 2 h after hormone treatment using a quantitative proteomics approach in which 3,514 proteins were reliably quantified. A comparison of the ,100 differentially expressed proteins at each the time point showed limited overlap, suggesting a dynamic and transient response to exogenous auxin. Several proteins with established roles in auxin-mediated root development exhibited altered abundance, providing support for this approach. While novel targeted proteomics assays demonstrate that all six auxin receptors remain stable in response to hormone. Additionally, 15 of the top responsive proteins display root and/or auxin response phenotypes, demonstrating the validity of these differentially expressed proteins. Auxin signaling in roots dictates ...
A study was conducted to determine the effects of different levels of apple juice concentrate (AJC), blackcurrant concentrate (BCC) and pectin on the moisture content, water activity, color, texture and ascorbic acid content of apple-blackcurrant fruit leather using the response surface methodology. The results showed the moisture content increased with increasing pectin level and with greater increases at higher AJC and BCC levels while the water activity increased with increasing pectin level and with increasing AJC level, at low pectin levels, but with decreasing AJC, at high pectin levels. The chroma decreased with increasing pectin level and with lower values at the middle AJC level. The puncturing force decreased with increasing AJC level but with a lower value at the middle pectin level. Lastly, the ascorbic acid content increased with increasing BCC level regardless of AJC and pectin levels. There is a need to reduce the drying temperature or time of apple-blackcurrant fruit leather just enough
The effects of pH of medium and molecular weight of chitosan on polyelectrolyte complex (PEC) formation between pectin and chitosan was investigated using capillary viscometry. The intrinsic viscosity of the polymers was determined using Huggins plot. PECs were formed between pectin and chitosan in the pH range 2.9-5.6, but no PEC was formed at pH 1.5. The proportion of pectin in pectin-chitosan PEC varied with pH of the medium due to different levels of ionisation of the polymers and also probably due to the flexibility of pectin molecule. The amount of pectin in the PEC increased with a decrease in pH while that of chitosan increased with an increase in pH of medium. Linear relationships were established between the pH of media used and the weight fraction of pectin required for optimal PEC formation with molecular weight grades of chitosan. Molecular weight of chitosan appeared to have no effect (p,0.05) on the optimal ratio of pectin:chitosan required for PEC formation but intrinsic ...
The citrus by-products pectin and polyphenols were obtained from Citrus x lantifolia residues. The use of acid type, solute-solvent ratio, temperature, and extraction time on pectin yield recovery was evaluated using a factorial design 34; pectin physicochemical characterization, polyphenol profile, and antioxidant activity were also determined. Results indicated a total polyphenol content of 3.92 ± 0.06 mg Galic Acid Equivalents (GAE)/g of citrus waste flour in dry basis (DB), with antioxidant activity of 74%. The presence of neohesperidin (0.96 ± 0.09 mg/g of citrus flour DB), hesperidin (0.27 ± 0.0 mg/g of citrus flour DB), and ellagic acid (0.18 ± 0.03 mg/g of citrus flour DB) as major polyphenols was observed. All of the factors evaluated in pectin recovery presented significant effects (p < 0.05), nevertheless the acid type and solute-solvent ratio showed the greatest effect. The highest yield of pectin recovery (36%) was obtained at 90 °C for 90 min, at a ratio of 1:80 (w/v) using citric
Abstract. Background & Aims: Low-molecular-weight citrus pectin (LCP) is a complex polysaccharide that displays abundant galactosyl (i.e., sugar carbohydrate) residues. In this study, we evaluated the anti-tumor properties of LCP that lead to Bcl-xL -mediated dampening of apoptosis in gastrointestinal cancer cells.. Methods: We used AGS gastric cancer and SW-480 colorectal cancer cells to elucidate the effects of LCP on cell viability, cell cycle and apoptosis in cultured cells and tumor xenografts.. Results: Significantly decreased cell viabilities were observed in LCP treated AGS and SW-480 cells (P,0.05). Cell cycle-related protein expression, such as Cyclin B1, was also decreased in LCP treated groups as compared to the untreated group. The AGS or SW-480 cell-line tumor xenografts were significantly smaller in the LCP treated group as compared the untreated group (P,0.05). LCP treatment decreased Galectin-3 (GAL-3) expression levels, which is an important gene in cancer metastasis that ...
MATERIALS AND METHODS. Plant material. Flax (Linum usitatissimum L., var. Mogilevski) plants from the collection of the All-Russian Flax Research Institute (Torzhok, Russia) were used. The plants were grown in natural condition, in boxes with a 50-cm soil layer, in the open air, under natural light, and with daily watering. Stem peels (fibrous parts) of 10-cm-long segments located below the snap point [21] were taken at the period of rapid growth (40 days after sowing) and used for rhamnogalacturonan I isolation. Fibers isolated from mature flax stems (100 days after the sowing) were used for extraction of rhamnogalacturonan I from the cell wall.. Rhamnogalacturonan I isolation and purification. Flax fiber rhamnogalacturonan I, which is not incorporated in the cell wall (RGf), was isolated as a high molecular weight polymer from the supernatant obtained after tissue homogenization in buffer (10 mM NaOAc, pH 5.0, 10 ml per g of tissue). Polymers present in the clarified homogenate were filtered ...
Modified Citrus Pectin (MCP) is a natural supplement derived from the white inner peel of citrus fruit. Research shows that it may support heavy metal detoxification, without causing adverse side-effects or disturbing essential minerals.
Polygalacturonase (EC 3.2.1.15), also known as pectin depolymerase, PG, pectolase, pectin hydrolase, and poly-alpha-1,4-galacturonide glycanohydrolase, is an enzyme that hydrolyzes the alpha-1,4 glycosidic bonds between galacturonic acid residues. Polygalacturonan, whose major component is galacturonic acid, is a significant carbohydrate component of the pectin network that comprises plant cell walls. Therefore, the activity of the endogenous plant PGs works to soften and sweeten fruit during the ripening process. Similarly, phytopathogens use PGs as a means to weaken the pectin network, so that digestive enzymes can be excreted into the plant host to acquire nutrients. This enzymes multiple parallel beta sheets form a helical shape that is called a beta helix. This highly stable structure, thanks to numerous hydrogen bonds and disulfide bonds between strands, is a common characteristic of enzymes involved in the degradation of pectin. The interior of the beta helix is hydrophobic. X-ray ...
Background and Aims. Aluminium (Al) toxicity is one of the most severe limitations to crop production in acid soils. Inhibition of root elongation is the primary symptom of Al toxicity. However, the underlying basis of the process is unclear. Considering the multiple physiological and biochemical functions of pectin in plants, possible involvement of homogalacturonan (HG), one of the pectic polysaccharide domains, was examined in connection with root growth inhibition induced by Al.. Methods. An immunolabelling technique with antibodies specific to HG epitopes (JIM5, unesterified residues flanked by methylesterifed residues; JIM7, methyl-esterified residues flanked by unesterified residues) was used to visualize the distribution of different types of HG in cell walls of root apices of two maize cultivars differing in Al resistance.. Key Results. In the absence of Al, the JIM5 epitope was present around the cell wall with higher fluorescence intensity at cell corners lining the intercellular ...

In recent years, considerable attention has been paid to the use of microorganisms in industrial fermentation processes, especially enzyme production. There has been a huge interest in growing fungi having the ability to produce pectinase, an enzyme which degrade pectin, which can be used in industrial fruit processing.. Pectin is an heteropolysaccharide present in the cell wall of terrestrial plant.During this processing, they play a crucial role in the extraction and clarification of fruit juice. In order to obtain concentrates of high quality, it is essential to degrade pectin using pectinolytic enzymes, hence clarifying the juice.. Microbial enzymes are commercially produced either through solid substrate fermentation or submerged fermentation. These techniques for enzyme production are generally conducted in stirrer tank reactors under aerobic conditions using batch or fed-batch system. Solid substrate fermentation (SSF) incorporate microbial growth and product formation on or within ...

The bioaccessibility of peptides and amino acids (AA) during in vitro gastrointestinal digestion of proteins from acid dairy gel (or yogurt) containing different polysaccharides (PS) was investigated. The nature of added PS was shown to modulate the kinetics of proteins gastric digestion. Yogurts with β-glucan and with pectin showed faster proteolysis, lower release of large peptides, and a higher proportion of free AA than those with starch or without PS. Segregation between β-glucan and dairy proteins was hypothesized to explain faster proteolysis by concentration of enzymes and proteins in a separated phase considered as micro-reactors. Kinetics of protein digestion during the buccal phase was not affected by the presence of PS in yogurts. At the beginning of duodenal phase yogurts with starch and with pectin showed a higher degree of hydrolysis; at the end of this phase proteins were fully digested (no native protein left and bioaccessible AA was increased). ...

Here I am, back to report on the success of my trying to re-jell the delicious red currant syrup my first effort yielded. The link Dilbert provided was extremely helpful, and I followed the instructions to the letter. The result was a perfectly set jelly! Thank you so much. Now, the down side. In my original effort, I cut the sugar a bit, as I like red currant jellys natural tartness. Also, as I mentioned in my original post, I had to halve the recipe, because I didnt harvest 4 lbs of currants. The link Dilbert provided required an additional 3 T of sugar per cup of measured juice, and several teaspoons of lemon juice, as well as about a teaspoon of additional pectin per cup of juice. I added this, exactly as instructed, and the instructions clarified whether or not to stir the pectin in (do) and exactly how long to boil (1 minute), stirring vigorously during this phase. The final product was in fact a little too sweet, and the lemon juice, unfortunately, changed the taste of the red currants, ...

Alkalophilic Bacillus include industrially important species since they can produce many extracellular enzymes which are active and stable at high pH values.These alkaline enzymes (proteases, amylases, xylanases, cellulases, lipases and pectinases) find use in various field of industry such as leather, detergent, paper industries and waste water treatment.Isolation of diverse bacteria plays an important role in finding novel enzymes with improved characteristics. The aim of this study was therefore to screen for alkaline extracellular enzymes of alkalophilic Bacillus isolated from soil, horse feces and leather processing and to characterize these strains by phenotypic tests and by 16S-ITS rDNA based RFLP.At the end of the study, rod-shaped, endospore forming and Gram positive 116 strains were identified as Bacillus. Ten of the 116 strains were found to be obligate alkalophilic. 91 protease, 77 amylase, 18 xylanase, 3 cellulase, 74 pectinolytic enzyme (71 polygalacturonic acid degrading and 72 ...
Evidence strongly supported a link between inflammation and cancer. Patients with colitis have high risk for development of colon cancer. Nuclear factor-kappa B (NF-B), partially induced by lipopolysaccharide (LPS) binding to Toll-like receptor (TLR) 4, is a vital molecule in supervising the transformation of colitis to colon cancer. It could be a good strategy to prevent colitis carcinogenesis for targeting LPS/TLR4/NF-B pathway. In the present study, we obtained an oligogalactan composed of five galacturonic acids from apple pectin and evaluated its protective efficacy on intestinal toxicities and carcinogenesis in a mouse model of colitis-associated colon cancer induced by 1,2-dimethylhydrazine and dextran sodium sulfate (DSS). The apple oligogalactan (AOG) was highly effective against intestinal toxicities and carcinogenesis and decreased the elevated levels of TLR4 and tumor necrosis factor- (TNF-) induced by inflammation in vivo in this model system. In vitro studies, AOG alone only ...
Agroindustrial waste is considered to be a valuable secondary raw material for various industrial processes and the separation of various functional constituents due to its high availability and an interesting chemical composition, while simultaneously reducing environmental burden and costs. The aim of this paper was to investigate the use of a chelating agent (EDTA) and the influence of extraction parameters on the yield and composition of pectin from onion biomass waste. For the purpose of characterisation of pectin isolates and of residues after extraction, a characteristic method of high performance liquid chromatography (HPLC) was developed. The HPLC method determines 7 neutral sugars and 2 uronic acids, whereby the structural carbohydrates occupy most of the carbohydrate fraction. The highest yield of pectin substances was obtained in the sample extracted at elevated temperature and elevated pH of solvent. All pectin isolates had a dominant share of galacturonic acid, hence the most ...

The aloe vera plant stores water in its leaves, which allows it to thrive during arid periods in climates where rainfall is sporadic. Gel is the terminology used to describe the mucilaginous material obtained from the parenchyma tissue of the plant. This slimy substance is approximately 99.0 - 99.5% water. The remaining 0.5-1.0% is comprised of a highly complex mixture of many components consistently mainly of a number of polymeric carbohydrate molecules called polysaccharides which contain building blocks of different small molecule sugars (monosaccharides). While a number of polysaccharides are present, the primary ones are acetylated mannan and pectin substance. These polymers provide the physical structure to this highly aqueous system which gives it its mucilaginous character. Mannans are also responsible for binding cellulose and for acting as signaling molecules for plant growth. Pectin substance includes several closely-related polysaccharides such as pectin, pectic acid, and ...
Arabinogalactan proteins (AGPs) and pectins were detected in the floral buds of cucumber (Cucumis sativus L.) during its sex determination using the following monoclonal antibodies: MAC 207 (recognizes AGP epitopes); JIM 8 (recognizes a subset of AGP epitopes); and JIM 5 and JIM 7 (epitopes of pectins esterified to various degrees). In the stem apex meristem (SAM) of the cucumber, epitopes of MAC 207, JIM 7, and JIM 5 were localized in the cells from second to third peripheral layers when the sex organ primodium began to differentiate; epitopes of MAC 207 and JIM 5 were also detected in the ragged edge cells. A very dense labeling signal with MAC 207 was observed in the carpel and pistil primodium. The AGP epitopes recognized by JIM 8 were localized in the anther of the male flower and the anther-like portion of the stagnant stamen of the female flower.

It is a fact that lemons (and citrus fruits in general) provide us many useful nutritional and health benefits and they might possess some substantial anti-cancer properties. Lemons and other citrus fruits contain the naturally occurring substances Modified Citrus Pectin and Limonoids, and few studies that looked into their anti-carcinogenic properties have found some promising results, but not enough research is done to prove its effects on Humans. As of this writing, no reputable scientific or medical studies have reported that lemons can definitely act as remedy against cancers of all types, or that they are 10,000 times stronger than chemotherapy. So the stories saying so are hoaxes.. Nonetheless, lemons can be consumed as an essential component of a healthy diet.
