N2 - Low temperatures during rice (Oryza sativa L.) pollen development cause pollen sterility and decreased grain yield. We show that the time of highest sensitivity to cold coincides with the time of peak tapetal activity: the transition of the tetrad to early uni-nucleate stage (young microspore, YM stage). Low temperatures at this stage of pollen development result in an accumulation of sucrose in the anthers, accompanied by decreased activity of cell wall bound acid invertase and depletion of starch in ...
Indole-3-acetic acid (IAA) synthesis is required for grain-fill in maize and appears to be regulated by cell-wall invertase (CWIN) activity. OsYUC12 is one of three IAA biosynthesis genes we previously reported as expressed during early rice grain development, correlating with a large increase in IAA content of the grain. This work aimed to investigate further the role of OsYUC12 and its relationship to CWIN activity and invertase inhibitors (INVINH). The analysis shows a brief peak of OsYUC12 expression early in endosperm development. Meta-analysis of microarray data, confirmed by quantitative expression analysis, revealed that OsYUC12 is coexpressed with OsIAA29, which encodes an unusual AUX/IAA transcription factor previously reported as poorly expressed. Maximum expression of OsYUC12 and OsIAA29 coincided with maximum CWIN activity, but also with a peak in INVINH expression. Unlike ZmYUC1, OsYUC12 expression is not reduced in the rice CWIN mutant, gif1. Several reports have investigated CWIN
In the process of protein secretion, amino-terminal signal sequences are key recognition elements; however, the relation between the primary sequence of an amino-terminal peptide and its ability to function as an export signal remains obscure. The limits of variation permitted for functional signal sequences were determined by replacement of the normal signal sequence of Saccharomyces cerevisiae invertase with essentially random peptide sequences. Since about one-fifth of these sequences can function as an export signal the specificity with which signal sequences are recognized must be very low.. ...

Dominant and recessive mutations at the SSN20 locus were previously isolated as extragenic suppressors of mutations in three genes (SNF2, SNF5, and SNF6) that are required in trans to derepress invertase expression. All ssn20 alleles cause recessive, temperature-sensitive lethality. In this study we cloned the SSN20 gene, identified a 4.6-kilobase poly(A)-containing RNA, and showed that disruption of the gene is lethal in a haploid cell. Genetic mapping of SSN20 to a locus on chromosome VII 10 centimorgans distal to cly8 led to the finding that SSN20 is the same gene as SPT6, which affects expression of delta insertions in the 5 noncoding region of HIS4 (F. Winston, D. T. Chaleff, B. Valent, and G. R. Fink, Genetics 107:179-197, 1984). We also showed that an ssn20 mutation restored expression of secreted invertase from deletions of the SUC2 upstream regulatory region; ssn20 restored derepression of SUC2 mRNA in strains with a SUC2 upstream region deletion or a snf2 mutation. Increased or ...

AB : A ` particulate ` invertase preparation of low activity (sedimenting in the 900 g fraction) was extracted from the stalk and mesocarp tissues of coconut (Cocos nucifera L.). The activity o invertase was found to increase linearly with the time of incubation (0 - 3h). Initial velocity was directly proportional to enzyme concentration, only in the low concentration ranges. The initial velocity decreased at enzyme concentrations higher than 0.13 mg protein per 2.0 ml of incubation mixture. Treatment of the particulate enzyme with 0.1 present and 0.5 present (v/v) of the nonionic surface active agent, Triton X - 100, solubilized 71 percent and 76 percent of the invertase. Incorporation of the non-acidic thiol, mercaptoethanol into the reaction mixture, caused significant activation of the invertase. This suggested the possibility of an SH group participating in the catalytic activity of the enzyme. In addition, mercaptoethanol may cause enzyme reactivation by reducing the quinones formed by the ...
A multi-year research on the influence of donor-acceptor relations between photosynthetic and assimilate-consuming organs on regulation of plant photosynthesis has been summarized. Cause and effect relationships between chloroplast photochemical reactions, CO|sub|2|/sub| assimilation and oxygen photosynthetic metabolism, transport of sugars in the phloem, apoplastic invertase and leaf stomata activity have been established. A concept, according to which the regulation of photosynthesis at the level of an assimilate donor leaf with the change of illumination or export of products of photosynthesis is effectuated as follows, has been introduced. In case of deficiency of products of chloroplast photochemical reactions there occurs incomplete regeneration of resulting primary CO|sub|2|/sub| fixation products and rapid accumulation of oxygenated substances in cells, vacuoles and the apoplast of the leaf. Apoplastic fluid pH decrease activates the invertase and intensifies the sucrose splitting in the
A novel cDNA clone, functionally expressed in E. coli, was isolated from a L. temulentum L. cDNA library. The expressed protein hydrolysed sucrose with an apparent Km of approximately 18 mM, and produced equi-molar concentrations of glucose and fructose. Optimum activity was observed at pH 7-7.5; there was little or no activity at pH 5.5. The expressed protein did not hydrolyse raffinose, stachyose or maltose. The activity of the expressed protein was inhibited by fructose (50% at 15 mM) and TRIS (50% at 2.5 mM), but was not affected by MgCl2, CaCl2 or MnCl2. These findings suggest that this cDNA clone encodes for an alkaline/neutral invertase. Sequence analysis revealed little homology with published sequences for acid invertase, however the invertase motif (NDPN) identified in other invertases was present. Expression studies show that the gene encoding for this enzyme is not regulated by sucrose accumulation in leaf ...

Refiners syrup (also called "golden syrup") is made, as the name implies, at a sugar refinery, not at the sugar mill which is where molasses is produced. Its a by product of the making of white sugar, the final "molasses" thats produced when white sugar is centrifuged. It contains mainly sucrose and water when its first spun out, but is treated with acid (or sometimes the enzyme invertase) to create a proportion of invert sugar. For more on sugar refining, see my (now integrated) primer on sugar making.. Refiners syrup can make a fine alternative to either molasses or corn syrup depending on the application, though since it tastes every bit as sweet as table sugar you need to be careful about overloading your recipe with sweetness.

With yeast this hypothesis can easily be tested, because a whole set of temperature-sensitive secretory mutants (Schekman, 1985) with defects at all stages along the secretory pathway of proteins is available. Secretory mutants selected for this study are listed in Table 1. If sphingolipids reach the plasma membrane by a process linked to protein secretion, temperature shift of secretory mutants from 24 to 37°C should not only inhibit protein secretion, but also affect the intracellular translocation of sphingolipids. Again, the kinetic and biochemical properties of cholesterol and marker protein transport to the PM are compared. The t1/2 of cholesterol transport to the PM was approximately 10 min (Kaplan and Simoni, 1985a), a value within the bounds of estimates of bulk membrane flow from the ER to the plasma membrane (Wieland et aL, 1987). This cholesterol transport required metabolic energy, exhibited a dramatic cold-sensitivity as transport ceased at 15°C, and labeled cholesterol ...

Sorbitol dehydrogenase (SDH, EC 1.1.1.14) was extracted, as described by Park et al. (2002) and Yamaguchi and Kanayama (1996) with some modifications. 0.5 g frozen sample was homogenized in 2 ml of 200 mM potassium phosphate buffer (pH 7.8) containing 1 mM EDTA, 10 mM sodium ascorbate, 1 mM dithiothreitol (DTT), 0.15% (v/v) Triton X-100, 1% (w/v) BSA and 2% (w/v) insoluble polyvinylpolypyrrolidone (PVPP). The homogenate was centrifuged at 13,000×g for 15 min at 4°C. 1 ml of the supernatant was desalted with a Sephadex G25 PD-10 column (GE Healthcare, UK) equilibrated with 125 mM Tris-HCl (pH 9.6). SDH activity was measured in a 1 ml reaction mixture containing 500 mM Sorbitol, 1 mM NAD+ and desalted extract in 125 mM Tris-HCl (pH 9.0), and NADH production was determined at 340 nm..

Sugarcane is the most efficient large-scale crop capable of supplying sufficient carbon substrate, in the form of sucrose, needed during fermentative feedstock production. However, sucrose metabolism in Escherichia coli is not well understood because the two most common strains, E. coli K-12 and B, do not grow on sucrose. Here, using a sucrose utilizing strain, E. coli W, we undertake an in-depth comparison of sucrose and glucose metabolism including growth kinetics, metabolite profiling, microarray-based transcriptome analysis, labelling-based proteomic analysis and 13C-fluxomics. While E. coli W grew comparably well on sucrose and glucose integration of the omics, datasets showed that during growth on each carbon source, metabolism was distinct. The metabolism was generally derepressed on sucrose, and significant flux rearrangements were observed in central carbon metabolism.These included a reduction in the flux of the oxidative pentose phosphate pathway branch, an increase in the ...

Immunoglobulin heavy-chain binding protein (BiP, GRP-78) associates tightly in the endoplasmic reticulum (ER) with newly synthesized proteins that are incompletely assembled, have mutant structures, or are incorrectly glycosylated. The function of BiP has been suggested to be to prevent secretion of incorrectly folded or incompletely assembled protein, to promote folding or assembly of proteins, or to solubilize protein aggregates within the ER lumen. Here we examine the interaction of BiP with newly synthesized polypeptides in an in vitro protein translation-translocation system. We find that BiP forms tight complexes with nonglycosylated yeast invertase and incorrectly disulphide-bonded prolactin, but does not associate detectably with either glycosylated invertase or correctly disulphide-bonded prolactin. Moreover, BiP associates detectably only with completed chains of prolactin, not with chains undergoing synthesis. We conclude that BiP recognizes and binds with high affinity in vitro to ...

Microbes emit volatile compounds that affect plant growth and development. However, little or nothing is known about how microbial emissions may affect primary carbohydrate metabolism in plants. In this work we explored the effect on leaf starch metabolism of volatiles released from different microbial species ranging from Gram-negative and Gram-positive bacteria to fungi. Surprisingly, we found that all microbial species tested (including plant pathogens and species not normally interacting with plants) emitted volatiles that strongly promoted starch accumulation in leaves of both mono- and dicotyledonous plants. Starch content in leaves of plants treated for 2 d with microbial volatiles was comparable with or even higher than that of reserve organs such as potato tubers. Transcriptome and enzyme activity analyses of potato leaves exposed to volatiles emitted by Alternaria alternata revealed that starch overaccumulation was accompanied by up-regulation of sucrose synthase, invertase inhibitors, ...
The consumption of netted muskmelons (Cucumis melo L. Reticulatus group) has raised health concerns due to pathogenic bacteria attaching to sites on the netted rind inaccessible to sanitation. The purpose of this study was to compare 1) the enzymic and nonenzymic antioxidant capacity between representative cultivars of netted muskmelon and both green- and orange-fleshed honey dew muskmelons during storage for 17 days and 2) levels of non-nutrient phytochemicals between these genotypes in consideration of ultimately substituting netted orange-fleshed with non-netted orange-fleshed muskmelon. Netted muskmelon (`Cruiser), green-fleshed (`Honey Brew), and orange-fleshed (`Orange Dew) muskmelons were harvested in Texas at the beginning (21 May) and at the end (11 June) of the production season in 2004. Fruit were analyzed immediately (day 0) or stored simulating retail conditions for 7 or 14 days at 7 °C and 95% ± 2% relative humidity plus 3 days at 21 °C. Both `Orange Dew and `Honey Brew ...

formula I or ketoamide intermediates to prepare compounds of formula I is to to add 1- 20 equivalents but most preferably 5 equivalents of a commercially available solution of 32% peracetic acid in dilute aq acetic acid to the reaction flask containing the completed reaction described in Step A. The reaction is typically stirred at the same temperature at which the alkylation reaction was conducted (for the Step A reactions with an acid chloride in THF -78° and for the step A reactions in DMF ~ -42°) for a period of Ih and then allowed to warm to ambient temperature if not already at that tmeperature. The reaction mixture is then either allowed to react further or immediately diluted with saturated aq. ammonium chloride and EtOAc. For relatively insoluble acid products which precipatate, the resultant precipitate is isolated by filtration as the oxoacetyl product ZC(O)C(O)Y. For organic soluble acid products, the acid is extracted into the organic layer and the layers separated. The organic ...

Four monoclonal antibodies (McAbs) were generated against the soluble extracellular acid phosphatase (EC 3.1.3.2) (S-AcP) of Leishmania donovani. These were detected in the primary screen using an ELISA with promastigote culture supernatants as antigen. Three of the McAbs demonstrated bound S-AcP from such culture supernatants in an enzyme activity binding assay. All immunoprecipitated metabolically labeled S-AcP but none showed any binding to the promastigote surface by indirect immunofluorescence. Moreover, none reacted with Triton X-100 solubilized plasma membranes by immunoprecipitation or Western blotting. These results demonstrated that the McAbs did not recognize the surface membrane bound acid phosphatase, but were specific for the extracellular soluble enzyme. Further, none of the antibodies immunoprecipitated any of the five human acid phosphatase isozymes or reacted with them in Western blots or the enzyme activity binding assay. Therefore, they are specific for the parasite-derived ...

Golden Syrup - Lyles is the only brand I have ever seen in the U.S. as this is primarily a British product. Golden syrup is a pale version of Treacle. This is a form of inverted sugar. Inverted sugar is created by adding an enzyme (invertase) to a cane sugar/water solution in the presence of an acid... say lemon juice. The enzyme breaks the Glucose-Fructose bond, so you end up with a syrup that has free glucose and free fructose. Golden syrup differs from High-Fructose corn syrup in that the process ends with the breaking of the glucose/fructose bond. HFCS undergoes and extra enzymatic step that actually changes some of the glucose into fructose using Xylose Isomerase. Golden syrup IS sweeter than regular granulated sugar even though its made from cane juice.... this is due to the free fructose, making it similar to honey both in texture and sweetening power. It is often used as a substitute by persons who abstain from honey ...
Invertase was immobilised on microporous montmorillonite K-10 via adsorption and covalent binding. The immobilised enzymes were tested for sucrose hydrolysis activity in a batch reactor. Km for immobilised systems was greater than free enzyme. The immobilised forms could be reused for 15 continuous cycles without any loss in activity. After 25 cycles, 85% initial activity was retained. A study on leaching of enzymes showed that 100% enzyme was retained even after 15 cycles of reuse. Leaching increased with reaction temperature. Covalent binding resisted leaching even at temperatures of 70 °C ...

N2 - MUC1 is efficiently delivered to the apical surface of polarized Madin-Darby canine kidney (MDCK) cells by transit through apical recycling endosomes, a route associated with delivery of apical proteins with glycan-dependent targeting signals. However, a role for glycans in MUC1 sorting has not been established. A key feature of MUC1 is a heavily O-glycosylated mucin-like domain with a variable number of nearly perfect tandem repeats and adjacent imperfect repeats. Metabolic labeling, cell surface biotinylation, immobilized lectins, and confocal immunofluorescence microscopy were used to characterize the polarized delivery of MUC1 mutants and chimeras in MDCK cells to identify the apical targeting signal. Both ...
Introduction. Biology coursework Investigation- Affect of sucrose concentration on the rate of respiration. Planning Aim and Background information The aim of this investigation is to find out how the affect of changing the sucrose concentration affects the rate of respiration of yeast. The reaction can be measured by the amount of carbon dioxide given of by yeast and ethanol is also produced as a result of the reaction. Yeast (Saccharomyces cerevisiae) is a unicellular fungus, which is frequently used in baking. The precise classification is a field that uses the characteristics of the cell, ascospore and colony. Physiological characteristics are also used to identify species. One of the better-known characteristics is the ability to ferment sugars for the production of ethanol. Budding yeasts are true fungi of the phylum Ascomycetes, class Hemiascomycetes. The true yeasts are separated into one main order Saccharomycetales. Yeasts multiply as single cells that divide by budding (eg ...

Fruits of cv. Fortune mandarin were periodically :harvested throughout the ripening period to evaluate changes in carbohydrate content and metabolism in flavedo tissue and to determine the potential role of carbohydrates in the tolerance of citrus fruit to chilling injury (CI). Sucrose showed little change in the flavedo during the season, but fructose and glucose increased, in nearly equal amounts, throughout the fall and winter, reaching a maximum in January. Starch levels were less abundant than soluble carbohydrates and rose continuously until March. Sucrose phosphate synthase (SPS; EC 4.1.14) activity decreased from December throughout ripening. Changes in sucrose synthase (SS; EC 2.4.1.13) and acid and alkaline invertase (Inv; EC 3.2.1.26) activities correlated with changes in the reducing sugars, but acid invertase was less active than the other sucrose-metabolizing enzymes. Carbohydrate changes in the flavedo of Fortune mandarins with fruit maturity appear not to be related to the ...
