A hemicellulose (also known as polyose) is one of a number of heteropolymers (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all terrestrial plant cell walls. [1] Cellulose is crystalline, strong, and resistant to hydrolysis.
Endo-1,4-β-xylanase (EC 3.2.1.8, systematic name 4-β-D-xylan xylanohydrolase) is any of a class of enzymes that degrade the linear polysaccharide xylan into xylose, [1] thus breaking down hemicellulose, one of the major components of plant cell walls: Endohydrolysis of (1→4)-β-D-xylosidic linkages in xylans
Xylan (/ ˈ z aɪ l æ n /; [3] / ˈ z aɪ l ən / [4]) (CAS number: 9014-63-5) is a type of hemicellulose, a polysaccharide consisting mainly of xylose residues. It is found in plants, in the secondary cell walls of dicots and all cell walls of grasses. [5]
Proteins: Structure, Function, and Bioinformatics is a monthly peer-reviewed scientific journal published by John Wiley & Sons, which was established in 1986 by Cyrus Levinthal. The journal covers research on all aspects protein biochemistry , including computation, function, structure, design, and genetics.
[1] [2] They are extremely common enzymes, with roles in nature including degradation of biomass such as cellulose , hemicellulose, and starch , in anti-bacterial defense strategies (e.g., lysozyme), in pathogenesis mechanisms (e.g., viral neuraminidases) and in normal cellular function (e.g., trimming mannosidases involved in N-linked ...
Most glycosyltransferase enzymes form one of two folds: GT-A or GT-B. Glycosyltransferases (GTFs, Gtfs) are enzymes that establish natural glycosidic linkages.They catalyze the transfer of saccharide moieties from an activated nucleotide sugar (also known as the "glycosyl donor") to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur ...
Function Describe the function of the transcribed protein. Interactions Optional section that lists proteins that the protein that is the subject of the article is known to interact with. Clinical significance List diseases or conditions that are a result of a mutation in the gene or a deficiency or excess of the expressed protein. History ...
Cell Biochemistry & Function is a peer-reviewed scientific journal published by Wiley-Blackwell. Its 2023 impact factor is 2.8. The journal was established in 1983 and the full archive is available online. The journal covers research on the molecular and biochemical mechanisms controlling cellular activity.
