Exopolysaccharide from Lactobacillus helveticus: identification of chemical structure and effect on biscuit duality
exopolysaccharide Lactobacillus helveticus biscuits xanthan LB-gum rheological properties chemical quality attributes sensory evaluation
2014/2/27
Exopolysaccharide (LB-gum) was produced from Lactobacillus helveticus by ethanol precipitation and gel-permeation chromatography. The structures of LB1 and LB2 were estimated by sugar composition anal...
Identification and Manipulation of Subsite Structure and Starch Granule Binding Site in Plant α-Amylase
α-amylase subsite starch granule
2008/4/20
In germinating plant seeds, α-amylases degrade starch accumulated in seeds, and that requires two functions: catalysis itself and starch granule binding ability. All plant α-amylases belong to the α-a...
Crystal Structure of GH54 α-L-Arabinofuranosidase and Unique Function of CBM42 Attached to It
crystallography glycoside hydrolase family 54 α-L-arabinofuranosidase arabinose-binding domain carbohydrate-binding module family 42
2008/4/20
As the first known structures of a glycoside hydrolase family 54 enzyme, we determined the crystal structures of free and arabinose-complex forms of α-L-arabinofuranosidase from Aspergillus kawachii I...
A Note on the Metabolic System for the Synthesis of the Tandem-Cluster Structure of Amylopectin in Rice Endosperm
amylopectin cluster rice starch branching enzyme starch debranching enzyme starch synthase
2008/4/20
The tandem-cluster structure of amylopectin must be a refined product that higher plants have evolved from the cluster-free random branched structure of glycogen. During the evolutionary process, plan...
Structure and Function of Exo-β-glucosaminidase from Amycolatopsis orientalis
Amycolatopsis orientalis exo-β-glucosaminidase chitosanase subsites chitooligosaccharides
2008/4/20
We cloned and sequenced the gene encoding exo-β-glucosaminidase (GlcNase) from Amycolatopsis orientalis, and found that the gene has an open reading frame of 1032 residues with a calculated molecular ...
Structure and Properties of Endosperm Starches from Cultivated Rice of Asia and Other Countries
rice starch indica japonica javanica super-long chain
2008/4/20
Starch granules were prepared from mature grains of 75 cultivars (23 indica, 27 Chinese indica, 6 japonica and 19 javanica) of rice originating in Asia and the other countries, including Brazil (4), C...
Structure and Thermal Properties of Several Acorn Starches
acorn starch amylose content characteristics of gelatinization chain length distributions of amylopectin
2008/4/20
Starch granules were prepared from 8 kinds of acorn; Kunugi (Quercus acutissima Carruth), Konara (Q. serrata Thunb), Naragashiwa (Q. aliena Blume), Shirakashi (Q. myrsinaefolia Blume), Matebashii (Lit...
Starch granules are synthesized in a semicrystalline structure and have characteristic morphology and properties depending on the botanical origin and the organ of the plant. Surface gelatinization st...
Studies on the Fine Structure and Functional Role of Plant Cell-wall Polysaccharides
xyloglucan feruloylated glucuronoarabinoxylan ferulic acid xyloglucanase
2008/4/19
This paper describes our studies on the fine structures and functions of the important hemicellulose, xyloglucan and glucuronoarabinoxylan, of the primary cell-walls of all higher plants. Xyloglucan: ...
Synthesis and Structure Analysis of Glucosylpsicose Produced by Cyclomaltodextrin Glucanotransferase
D-psicose cyclodextrin cyclomaltodextrin glucanotransferase
2008/4/19
Glucosylpsicose was synthesized by transglycosylation with α-cyclodextrin and D-psicose using cyclomaltodextrin glucanotransferase (EC 2.4.1.19; CGTase). The structure of glucosylpsicose was analyzed ...
Cyclization Reaction Catalyzed by Bacillus cereus Branching Enzyme, and the Structure of Cyclic Glucan Produced by the Enzyme from Amylose
