Simultaneous antisense inhibition of two starch-synthase isoforms in potato tubers leads to accumulation of grossly modified amylopectin. (1/137)

A chimaeric antisense construct was used to reduce the activities of the two major starch-synthase isoforms in potato tubers simultaneously. A range of reductions in total starch-synthase activities were found in the resulting transgenic plants, up to a maximum of 90% inhibition. The reduction in starch-synthase activity had a profound effect on the starch granules, which became extremely distorted in appearance compared with the control lines. Analysis of the starch indicated that the amounts produced in the tubers, and the amylose content of the starch, were not affected by the reduction in activity. In order to understand why the starch granules were distorted, amylopectin was isolated and the constituent chain lengths analysed. This indicated that the amylopectin was very different to that of the control. It contained more chains of fewer than 15 glucose units in length, and fewer of between 15 and 80 glucose units. In addition, the amylopectin contained more very long chains. Amylopectin from plants repressed in just one of the activities of the two starch-synthase isoforms, which we have reported upon previously, were also analysed. Using a technique different to that used previously we show that both isoforms also affect the amylopectin, but in a way that is different to when both isoforms are repressed together.  (+info)

Amylopectinosis in fetal and neonatal Quarter Horses. (2/137)

Three Quarter Horses, a stillborn filly (horse No. 1), a female fetus aborted at approximately 6 months of gestation (horse No. 2), and a 1-month-old colt that had been weak at birth (horse No. 3), had myopathy characterized histologically by large spherical or ovoid inclusions in skeletal and cardiac myofibers. Smaller inclusions were also found in brain and spinal cord and in some cells of all other tissues examined. These inclusions were basophilic, red-purple after staining with periodic acid-Schiff (both before and after digestion with diastase), and moderately dark blue after staining with toluidine blue. The inclusions did not react when stained with Congo red. Staining with iodine ranged from pale blue to black. Their ultrastructural appearance varied from amorphous to somewhat filamentous. On the basis of staining characteristics and diastase resistance, we concluded that these inclusions contained amylopectin. A distinctly different kind of inclusion material was also present in skeletal muscle and tongue of horse Nos. 1 and 3. These inclusions were crystalline with a sharply defined ultrastructural periodicity. The crystals were eosinophilic and very dark blue when stained with toluidine blue but did not stain with iodine. Crystals sometimes occurred freely within the myofibers but more often were encased by deposits of amylopectin. This combination of histologic and ultrastructural features characterizes a previously unreported storage disease in fetal and neonatal Quarter Horses, with findings similar to those of glycogen storage disease type IV. We speculate that a severe inherited loss of glycogen brancher enzyme activity may be responsible for these findings. The relation of amylopectinosis to the death of the foals is unknown.  (+info)

Essential arginine residues in maize starch synthase IIa are involved in both ADP-glucose and primer binding. (3/137)

The arginine-specific reagent phenylglyoxal inactivated the activity of maize starch synthase IIa (SSIIa), due to the modification of at least one arginine residue out of a possible 42. The addition of ADPGlc completely protected SSIIa from the inactivation, indicating that arginine may be involved in the interaction of this anionic substrate with SSIIa. However, site-directed mutagenesis of the conserved Arg-214 in SSIIa showed that this amino acid is important for apparent affinity of SSIIa for its primer (amylopectin and glycogen), as evidenced by a marked increase in the K(m) for primer upon substitution of this amino acid with no concomitant change in V(max), K(m) for ADPGlc, or secondary structure. Therefore, Arg-214 of SSIIa appears to play a role in its primer binding.  (+info)

Interaction with amylopectin influences the ability of granule-bound starch synthase I to elongate malto-oligosaccharides. (4/137)

This paper examines the properties in soluble form of two isoforms of starch synthase. One of these, granule-bound starch synthase I (GBSSI), is responsible for the synthesis of amylose inside the amylopectin matrix of the starch granule in vivo. The other, starch synthase II (SSII), is involved in amylopectin synthesis. Both isoforms can use amylopectin and malto-oligosaccharide as substrates in vitro. As well as acting as a substrate for GBSSI, amylopectin acts as an effector of this isoform, increasing the rate at which it elongates malto-oligosaccharides and promoting a processive rather than distributive mode of elongation of these compounds. The affinity of GBSSI for amylopectin as an effector is greater than its affinity for amylopectin as a substrate. The rate and mode of elongation of malto-oligosaccharides by SSII are not influenced by amylopectin. These results suggest that specific interaction with amylopectin in the matrix of the starch granule is a unique property of GBSSI and is critical in determining the nature of its products.  (+info)

In vitro utilization of amylopectin and high-amylose maize (Amylomaize) starch granules by human colonic bacteria. (5/137)

It has been well established that a certain amount of ingested starch can escape digestion in the human small intestine and consequently enters the large intestine, where it may serve as a carbon source for bacterial fermentation. Thirty-eight types of human colonic bacteria were screened for their capacity to utilize soluble starch, gelatinized amylopectin maize starch, and high-amylose maize starch granules by measuring the clear zones on starch agar plates. The six cultures which produced clear zones on amylopectin maize starch- containing plates were selected for further studies for utilization of amylopectin maize starch and high-amylose maize starch granules A (amylose; Sigma) and B (Culture Pro 958N). Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was used to detect bacterial starch-degrading enzymes. It was demonstrated that Bifidobacterium spp., Bacteroides spp., Fusobacterium spp., and strains of Eubacterium, Clostridium, Streptococcus, and Propionibacterium could hydrolyze the gelatinized amylopectin maize starch, while only Bifidobacterium spp. and Clostridium butyricum could efficiently utilize high-amylose maize starch granules. In fact, C. butyricum and Bifidobacterium spp. had higher specific growth rates in the autoclaved medium containing high-amylose maize starch granules and hydrolyzed 80 and 40% of the amylose, respectively. Starch-degrading enzymes were cell bound on Bifidobacterium and Bacteroides cells and were extracellular for C. butyricum. Active staining for starch-degrading enzymes on SDS-PAGE gels showed that the Bifidobacterium cells produced several starch-degrading enzymes with high relative molecular (M(r)) weights (>160,000), medium-sized relative molecular weights (>66,000), and low relative molecular weights (<66,000). It was concluded that Bifidobacterium spp. and C. butyricum degraded and utilized granules of amylomaize starch.  (+info)

Specificity of starch synthase isoforms from potato. (6/137)

In higher plants several isoforms of starch synthase contribute to the extension of glucan chains in the synthesis of starch. Different isoforms are responsible for the synthesis of essentially linear amylose chains and branched, amylopectin chains. The activity of granule-bound starch synthase I from potato has been compared with that of starch synthase II from potato following expression of both isoforms in Escherichia coli. Significant differences in their activities are apparent which may be important in determining their specificities in vivo. These differences include affinities for ADPglucose and glucan substrates, activation by amylopectin, response to citrate, thermosensitivity and the processivity of glucan chain extension. To define regions of the isoforms determining these characteristic traits, chimeric proteins have been produced by expression in E. coli. These experiments reveal that the C-terminal region of granule-bound starch synthase I confers most of the specific properties of this isoform, except its processive elongation of glucan chains. This region of granule-bound starch synthase I is distinct from the C-terminal region of other starch synthases. The specific properties it confers may be important in defining the specificity of granule-bound starch synthase I in producing amylose in vivo.  (+info)

Identification of the maize amyloplast stromal 112-kD protein as a plastidic starch phosphorylase. (7/137)

Amyloplast is the site of starch synthesis in the storage tissue of maize (Zea mays). The amyloplast stroma contains an enriched group of proteins when compared with the whole endosperm. Proteins with molecular masses of 76 and 85 kD have been identified as starch synthase I and starch branching enzyme IIb, respectively. A 112-kD protein was isolated from the stromal fraction by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and subjected to tryptic digestion and amino acid sequence analysis. Three peptide sequences showed high identity to plastidic forms of starch phosphorylase (SP) from sweet potato, potato, and spinach. SP activity was identified in the amyloplast stromal fraction and was enriched 4-fold when compared with the activity in the whole endosperm fraction. Native and sodium dodecyl sulfate-polyacrylamide gel electrophoresis analyses showed that SP activity was associated with the amyloplast stromal 112-kD protein. In addition, antibodies raised against the potato plastidic SP recognized the amyloplast stromal 112-kD protein. The amyloplast stromal 112-kD SP was expressed in whole endosperm isolated from maize harvested 9 to 24 d after pollination. Results of affinity electrophoresis and enzyme kinetic analyses showed that the amyloplast stromal 112-kD SP preferred amylopectin over glycogen as a substrate in the synthetic reaction. The maize shrunken-4 mutant had reduced SP activity due to a decrease of the amyloplast stromal 112-kD enzyme.  (+info)

Two loci control phytoglycogen production in the monocellular green alga Chlamydomonas reinhardtii. (8/137)

The STA8 locus of Chlamydomonas reinhardtii was identified in a genetic screen as a factor that controls starch biosynthesis. Mutations of STA8 cause a significant reduction in the amount of granular starch produced during nutrient limitation and accumulate phytoglycogen. The granules remaining in sta8 mutants are misshapen, and the abundance of amylose and long chains in amylopectin is altered. Mutations of the STA7 locus, which completely lack isoamylase activity, also cause accumulation of phytoglycogen, although sta8 and sta7 mutants differ in that there is a complete loss of granular starch in the latter. This is the first instance in which mutations of two different genetic elements in one plant species have been shown to cause phytoglycogen accumulation. An analytical procedure that allows assay of isoamylase in total extracts was developed and used to show that sta8 mutations cause a 65% reduction in the level of this activity. All other enzymes known to be involved in starch biosynthesis were shown to be unaffected in sta8 mutants. The same amount of total isoamylase activity (approximately) as that present in sta8 mutants was observed in heterozygous triploids containing two sta7 mutant alleles and one wild-type allele. This strain, however, accumulates normal levels of starch granules and lacks phytoglycogen. The total level of isoamylase activity, therefore, is not the major determinant of whether granule production is reduced and phytoglycogen accumulates. Instead, a qualitative property of the isoamylase that is affected by the sta8 mutation is likely to be the critical factor in phytoglycogen production.  (+info)

Glucose units are linked in a linear way with α(1→4) glycosidic bonds. Branching takes place with α(1→6) bonds occurring every 24 to 30 glucose units, resulting in a soluble molecule that can be quickly degraded as it has many end points onto which enzymes can attach. In contrast, amylose contains very few α(1→6) bonds, or even none at all. This causes amylose to be hydrolyzed more slowly, but have higher density and be insoluble.[clarification needed]. Its counterpart in animals is glycogen, which has the same composition and structure, but with more extensive branching that occurs every eight to 12 glucose units. Plants store starch within specialized organelles called amyloplasts. When energy is needed for cell work, the plant hydrolyzes the starch, releasing the glucose subunits. Humans and other animals that eat plant foods also use amylase, an enzyme that assists in breaking down amylopectin. Starch is made of about 70% amylopectin by weight, though it varies depending on the ...

Of the 22 species within the Oryza genus, only two, O. sativa and O. glaberrima, have been domesticated. Although food security is supported by accessing wild Oryza resources for new genes and alleles which enhance plant performance, wild Oryza grain properties have not been extensively studied. Evaluation of the grain physico-chemical properties of eight wild Oryza species found amylose content, amylopectin structure and cooking properties fell within a narrow range relative to cultivated rice. The amylopectin of the wild species had a lower proportion of short branch chains (DP 6-14) relative to cultivated rice and were all of high apparent amylose content and gelatinization temperature. The grain of the wild species did not elongate to the same extent as the cultivated rice and had lower viscosity parameters. These results highlight how significant physio-chemical changes have been made by human selection in the domestication of rice, especially japonica rice. The wild species may be useful for
Starchy foods Unlike sugary foods, the type of starch contained in a food is not as strong a predictor of its GI for a variety of reasons. There are two main types of starch - amylose and amylopectin, with amylose having a lower GI than amylopectin. So a food with more amylose may have a lower GI than one higher in amylopectin, but this is not always the case. This is partly because the starches in unrefined grains like hulled barley, brown rice or wheat berries are encapsulated by the germ and bran, which when left intact can make the starch - regardless of type - very hard to digest. Of course, this is why we process them to provide us with more digestible forms (e.g. pearl barley, white rice and bulgur) or into flour. We have found that the milling method (e.g., stone grinding versus modern steel roller milling) generally has a more significant effect on the ultimate GI of grain foods. Traditionally stone ground flours retain much more of the germ and bran and have more coarsely ground ...

Gene Name: AMY1, AMY2. 1. Overview (General). α-Amylase (1,4-α-D-glucan-glucanohydrolase, EC 3.2.1.1) is the primary digestive enzyme acting on starch or glycogen and is present in plants, animals, bacteria and fungi. Starch from plants is a high molecular weight polymer of glucose. It is made up of amylose, a straight-chain α-1,4 linked polymer of about 105units and amylopectin, a branched chain polymer with α1,4 linked glucose with branch points made up of α-1,6 linkages that contains about 106 units of glucose. Glycogen from animals is similar to amylopectin in structure but is smaller. α-Amylase cleaves the α-1,4 linkage when it is not next to a branch point or terminal glucose residue. Thus its products are maltose (2 glucose residues), maltotriose (3 glucose residues) and α-limit dextrins (5-6 residues which contain a branch point). In vertebrates, these are further cleaved to monosaccharides by the intestinal brush border enzymes isomaltase and maltase which hydrolyze the α-1,6 ...
There are two types of starch: amylose and amylopectin. Amylose is constructed with 1-4 linkage, but amylopectin is mixed of 1-4 and 1-6 linkage. Amylase can breakdown 1-4 linkage into maltose. However, it cannot breakdown 1-4 linkage. Dextrin is a disaccharide that composed of 1-6 linkage, which broke down from starch. To digest this, dextrinase is used ...
DISCUSSION. Dietary nutritional requirements of two species of penaeoids were investigated on the basis of their haemolymph metabolic contents and the apparent digestibility analysis to determine which the dietary components that were better assimilated are. The penaeoids shrimp do not present a dietary glucose requirement since this compound can come from the gluconeogenesis from the amino acids. Nevertheless, these organisms own a complete enzymatic structure for the digestion of proteins and polysaccharides, such as starch, glycogen, laminarin, and chitin that are natural components of their diet. (Tacon, 1990). The starch is a straight-chain consisting of glucose molecules linked together by a (1-4) bonds, conformed by two units amylose and amylopectin. The starches rich in amylose are poorly digestible because a-amylase cannot hydrolyze the amylase, in contrast, the starch rich in amylopectin is relatively well digested (Gaxiola et al., 2006). The cellulose is also a polymer of glucose but ...
With regard to the unexpected differences between cold and hot red potatoes, it is important to note that the results of a 2011 study by Kinnear et al. confirm that the latter is not an artifact of the Fernandes study. In their trial, the scientists from the University of Toronto found an average GI reduction of -37% (mean GI for the tested cultivars ~47), when the freshly boiled potatoes were refrigerated at 4°C for 24-28h before they were served to the 10 healthy study participants (Kinnear. 2011). As far as the reasons for this temperature-dependence of the glycemic index is concerned, Kinnear et al. speculate that it is an effect due to starch retrogradation, which is a process that takes place in gelatinized starch, when the amylose and amylopectin chains realign themselves and thusly causes the liquid to gel. This is quite interesting, as it stands in line with the low GI of the Marfona potato (cf. figure 1), the texture of which is described as waxy. The long-established relation of ...

PY - 1999/6/3. Y1 - 1999/6/3. N2 - Starch or pullulan was hydrolyzed using glucoamylase or pullulanase immobilized on N-isopropylacrylamide gel. The gel used is temperature sensitive; its mesh size becomes smaller at higher temperatures (30°C) and larger at lower temperatures (20°C). The molecular weight distribution of starch is wide and it consists of high-molecular-weight amylopectin, amylose and glucose. From the change in the chromatograms for the substrate and products it was found that the hydrolysis rate at 30°C was faster than that at 20°C for amylose, though it was the reverse for amylopectin. This finding suggests that the smaller molecular sized amylose can enter the gel phase at both temperature, while the larger molecular sized amylopectin can hardly do so; only the end group,which ...

The principle isomer of glucose is D-glucose (dextrose). It is the product of photosynthesis and the building block of a number of important carbohydrate polymers, including cellulose. In animals, glucose is the defining sugar of the blood. It is obtained from directly from dietary glucose, and from the More in the presence of amylase[ Amylase ] An enzyme which ...
White amorphous polysaccharide granules that compose about 70% of a corn kernel. Cornstarch is separated from the gluten and fibrous particles by sieving, wet grinding, then wash flotation. It is composed of 28% amylose and 75% amylopectin. When heated with water, cornstarch forms a medium viscosity solution that does not change with heating time. It thickens substantially on cooling to form an opaque gel. Cornstarch is the predominant starch used in North America as a thickener and filler in foods. It is used as an absorbent powder in baby powders and on the interior of some powdered latex gloves. Cornstarch is also used as an adhesive, a sizing agent, and a filler in waxes and plastics. ...

Due to the changes that occurred in the baking industry and the growing demand for natural products, clean label enzymes have gained more importance in the bread-making recipes in replacing additives such as oxidants or emulsifiers. The use of amylase from cereal, fungal or bacterial sources is known for many years. However, it is well acknowledged that cereal amylases, such as beta-amylase from soy flour or malt alpha-amylase and fungal ones have a limited effect against aging, whereas bacterial thermostable alpha-amylase has adverse effect on the quality of the finished products, leading to gummy and sticky crumb. Commercial amylases used in the baking industry are, in general, alpha-amylase, which hydrolyzes specifically, alpha-1,4-glycosidic linkages of amylose and amylopectin molecules in the starch. Based on these considerations, the aim of this study was to study the effect of lack of alpha- amylase in wheat flour used in the process of bread making. In this context, we intended to study ...

Introduction. Does Lowering Storage Temperature Increase the Reducing Sugar Content of Potatoes? Hypothesis: Potatoes kept at below freezing for a week will have significantly more reducing sugar in their cells than those kept at 5 degrees Celsius which will contain more than those kept at room temperature, displaying evidence of conversion of starch polysaccharides to maltose at low temperatures. Background The main food store in potatoes is starch, a mixture of the two insoluble polysaccharides amylose and amylopectin. Starch is a good storage material because it is insoluble and so can be accumulated without increasing the water potential of the potato cells. This is essential to the normal function of the cell as it prevents the cells being damaged by absorption of too much water by osmosis. When water freezes and turns to ice, its volume increases. The formation of ice crystals inside cells can cause serious and permanent structural damage to the cells. To reduce the problem of ice damage, ...
High-yield common buckwheat cv. Fengtian 1 (FT1) and tartary buckwheat cv. Jingqiao 2 (JQ2) were selected to investigate the characteristics of the grain-filling process and starch accumulation of high-yield buckwheat. FT1 had an average yield that was 43.0% higher than that of the control cv. Tongliaobendixiaoli (TLBDXL) in two growing seasons, while JQ2 had an average yield that was 27.3% higher than that of the control cv. Chuanqiao 2 (CQ2). The Richards equation was utilized to evaluate the grain-filling process of buckwheat. Both FT1 and JQ2 showed higher values of initial growth power and final grain weight and longer linear increase phase, compared with respective control. These values suggest that the higher initial increasing rate and the longer active growth period during grain filling play important roles to increase buckwheat yield. Similar patterns of starch, amylose and amylopectin accumulation were detected in common buckwheat, leading to similar concentration of each ...

To XXXX and anyone else interested in why gums can cause problems:. The very chemistry of what constitutes a gum is because the structure of the carbohydrates is such that it forms a latticework that confers on it a sticky-like, glue-like consistency. The diagram of the amylopectin molecule on page 30 of my book demonstrates this latticework. It is my hypothesis that at the point of the branches in the molecule is a chemical link called alpha 1-6 isomaltose which we cannot digest (cannot break two glucose molecules attached with that link). I believe that because we cannot digest it, it naturally moves down to the lower small intestine and colon as isomaltose and that a certain type of microorganism thrives on just that very disaccharide. This part of the hypothesis is very exciting to me as most corn products, all potatoes, and FOS have links similar to the isomaltose which remains undigested and goodness knows what is being nourished down there. From the LI ...

A card sheet including a top material layer having pre-cut weakened lines extending partially but not completely through the top material layer, the top material layer having a front side and a back side; and a starch composition layer applied to the back side of the top material layer, wherein at least a portion of the starch composition diffuses into the top material layer to a depth and renders the top material layer breakable along the weakened lines. A method of making the card sheet, including providing the top material layer, cutting partially through the top material layer; and applying a starch composition to form the starch composition layer on the back side of the top material layer; and at least partially removing any diluent present in the starch composition. The top material layer may be printable, and the card sheet may include a second top material layer.
To our knowledge the present paper shows for the first time the kinetic parameters of all the three starch branching enzyme (BE) isozymes, BEI, BEIIa and BEIIb, from rice with both amylopectin and synthetic amylose as glucan substrate. The activities of these BE isozymes with a linear glucan amylose decreased with a decrease in the molar size of amylose, and no activities of BEIIa and BEIIb were found when the degree of polymerization (DP) of amylose was lower than at least 80, whereas BEI had an activity with amylose of a DP higher than approximately 50. Detailed analyses of debranched products from BE reactions revealed the distinct chain length preferences of the individual BE isozymes. BEIIb almost exclusively transferred chains of DP7 and DP6 while BEIIa formed a wide range of short chains of DP6 to around DP15 from outer chains of amylopectin and amylose. On the other hand, BEI formed a variety of short chains and intermediate chains of a DP ≤40 by attacking not only outer chains but ...
Microstructural and rheological changes during gelatinisation are important indicators of starch functionality. A combined rheometer and optical microscope system (Rheoscope 1, Thermo Haake) was used to monitor the gelatinisation of different starches (maize starch containing 0%, 24%, 55% and 85% amylose; wheat starch and barley starch) suspended in a 0.1% guar solution (to minimise settling during the initial stages of gelatinisation). The 0.1% guar solution was selected after Rapid Visco Analyser, Modulated DSC and settling studies indicated that it minimised any effect on starch gelatinisation compared to carboxy methyl cellulose and xanthan. The Rheoscope study demonstrated that the viscosity of the starch during gelatinisation is related to changes in starch granules as a result of swelling. There was a two to threefold increase in starch granule size during the gelatinisation for all starches except for high amylose maize starches. Viscosity development during the gelatinisation was ...

Elymus (Poaceae) is a large genus of polyploid species in the wheat tribe Triticeae. It is polyphyletic, exhibiting many distinct allopolyploid genome combinations, and its history might be further complicated by introgression and lineage sorting. We focus on a subset of Elymus species with a tetraploid genome complement derived from Pseudoroegneria (genome St) and Hordeum (H). We confirm the species allopolyploidy, identify possible genome donors, and pinpoint instances of apparent introgression or incomplete lineage sorting. We sequenced portions of three unlinked nuclear genes-phosphoenolpyruvate carboxylase, β-amylase, and granule-bound starch synthase I-from 27 individuals, representing 14 Eurasian and North American StStHH Elymus species. Elymus sequences were combined with existing data from monogenomic representatives of the tribe, and gene trees were estimated separately for each data set using maximum likelihood. Trees were examined for evidence of allopolyploidy and additional ...

N2 - The effect of sucrose and sodium chloride (NaCl) on sago starch gelatinisation was investigated by differential scanning calorimetry (DSC). The gelatinisation of starch in the presence of low levels of water and high levels of sucrose was studied. The gelatinisation temperature was found to increase in the presence of sucrose, whereas the gelatinisation enthalpy was unaffected. The gelatinisation temperature range was not as broad in the presence of sucrose as without sucrose. Furthermore, the shape of the gelatinisation endotherm was changed by the addition of sucrose. The double endotherm obtained in limited water-starch systems was changed into a single endotherm, similar to the endotherm obtained in excess water-starch systems at ...
Starch is made of two homopolymers: amylose and amylopectin, themselves composed of D-glucose molecules. During the process of digestion, starch is dissociated into simple sugar molecules that are readily assimilated by the body. High amylose starch is more resistant to enzymatic digestion and is used as a food supplement for its high fiber content and low glycemic index. It is also used in the textile industry, cosmetic industry, pharmaceutical industry and the production of biodegradable plastics. We are currently working on the generation amylose-rich wheat lines. This is achieved by knocking out genes encoding starch-branching enzymes in the wheat genome. ...
Pullulanase (EC 3.2.1.41, limit dextrinase, amylopectin 6-glucanohydrolase, bacterial debranching enzyme, debranching enzyme, alpha-dextrin endo-1,6-alpha-glucosidase, R-enzyme, pullulan alpha-1,6-glucanohydrolase) is a specific kind of glucanase, an amylolytic exoenzyme, that degrades pullulan. It is produced as an extracellular, cell surface-anchored lipoprotein by Gram-negative bacteria of the genus Klebsiella. Type I pullulanases specifically attack α-1,6 linkages, while type II pullulanases are also able to hydrolyse α-1,4 linkages. It is also produced by some other bacteria and archaea. Pullulanase is used as a processing aid in grain processing biotechnology (production of ethanol and sweeteners). Pullulanase is also known as pullulan-6-glucanohydrolase (Debranching enzyme). Its substrate, pullulan, is regarded as a chain of maltotriose units linked by alpha-1,6-glycosidic bonds. Pullulanase will hydrolytically cleave pullulan (alpha-glucan polysaccharides).

The founding member of this family and the first module to be characterized is the first CBM found in the cell-wall anchored Amy13K from Eubacterium rectale (see Fig1). It was found to bind beta-cyclodextrin and glycogen with similar affinity, with slightly weaker affinity for maltoheptaose as determined by isothermal titration calorimetry. The module was also found to bind to corn starch granules, both from a wild-type source and from a high amylose source (HiMaize 260) with approximately equal affinity but did not demonstrate binding to potato starch or a chemically crosslinked starch (Fibersym) as determined via depletion assays. Binding to amylopectin and pullulan was also demonstrated via affinity electrophoresis. [1]. ...
Starch foams were prepared from four types of potato starch using two-step extrusion with an intermediate conditioning step at 53% relative humidity in order to control the moisture content. The moisture content was the driving force for the expansion during the second extrusion. The second extrusion was performed with two different dies in order to achieve differences in porosity of the materials. Glycerol in combination with water was used as plasticizer for the starches. The rheological properties of the melts and the moisture content of the starch materials prior to the expansion were determined. The porosity of the expanded structures was characterized using environmental scanning electron microscopy imaging and density measurements. The absorption capability of the starch-based foams was investigated using aqueous NaCl solutions, and the water uptake of thin starch-based films from humid air was also evaluated. Foams prepared from amylopectin potato starch were found to exhibit the highest

Starch is the most abundant storage glucan composed of two main structural components, amylose and amylopectin. Based on the rate of digestion, starch can be classified as rapidly digestible starch (RDS), slowly digestible starch (SDS), and resistant starch (RS) (Shi and Maningat 2013). In recent years, the effect of RS has drawn increasing interests in that it is not digested in the upper gastrointestinal tract, but is fermented in the large intestine and is beneficial for the gut environment (Lafiandra et al. 2014). Our recent research has shown that the applications of RS in foods can moderate the glycemic response and maintain a proper microorganism profile in the human gut (Zhou et al. 2013a, b). It has also been found that RS with a slow absorption and a low glycemic index can reduce blood lipids and improve insulin sensitivity, which can improve the glucose intolerance and insulin resistance (Goda et al. 2014). Previous studies have also shown that RS can reduce cholesterol and ...

Amylose: which is a straight chain of glucose molecules, like a string of beads. These tend to line up in rows and clump together so that they are hard to gelatinize and digest.. * Amylopectin: which is a string of glucose molecules with lots of branching points. These are thus larger and more open and the starch is easier to gelatinize and digest.. The starch occurs in small granules that have a core of starch surrounded by a network of protein.This starch forms a crystalline structure within this granule and is resistant to digestion when consumed in the raw state. This is why potatoes will give you a pain in the stomach when eaten raw. The table below shows the effect on cooking on the digestibility percentage of sweet potatoes (Canope et al. 1977). The table shows that cooking increases the digestibility of both energy and organic matter to the same extent. The biggest increase in digestibility was however noted on nitrogen (i.e. protein) digestibility. This response it observed due to the ...
Oryza sativa (rice) is a monocotyledonous flowering plant of the family Poaceae and is one of the most important crop plants in the world, providing the principal food source for half of the worlds population. Oryza sativa subsp. japonica is one of three major subspecies of rice, the others being indica and javanica. Oryza sativa subsp. japonica is short-grained and high in amylopectin so that the grains stick together when cooked, which distinguishes it from subsp. indica which is long grained and not sticky. Oryza sativa subsp. japonica is grown in dry fields, mainly in temperate or colder climates such as Japan.. Oryza sativa has a haploid chromosome number of 12, containing 370 Mb with 30,000 protein-coding genes. Rice was an obvious choice for the first whole genome sequencing of a cereal crop. It is the smallest of the major cereal crop genomes and is the easiest to transform genetically. The cultivar sequenced from the japonica subspecies was Nipponbare ...
Amylopectin A-The highly-digestible complex carbohydrate that is no better-worse, in fact-than table sugar.. So why not eat non-wheat grains all you want? If they dont cause appetite stimulation, behavioral outbursts in children with ADHD, addictive consumption of foods, dementia (i.e., gluten encephalopathy), etc., why not just eat them willy nilly?. Because they still increase blood sugar. Conventional wisdom is that these foods trend towards having a lower glycemic index than, say, table sugar, meaning they raise blood glucose less.. Thats true . . . but very misleading. Oats, for instance, with a glycemic index of 55 compared to table sugars 59, still sends blood sugar through the roof. Likewise, quinoa with a glycemic index of 53, will send blood sugar to, say, 150 mg/dl compared to 158 mg/dl for table sugar-yeah, sure, its better, but it still stinks. And thats in non-diabetics. Its worse in diabetics.. Of course, John Q. Internist will tell you that, provided your blood sugars ...

Hopefuly the protocol is clear from the table below, or you can also see the results in a Google Docs spreadsheet. Shortly after I woke up, and in a fasted state, I measured my blood glucose and insulin from a fingerstick made with a lancet.
