The invention relates to a method for degrading beta-1,4-glycosidic-bond-containing high-molecular-weight polysaccharides. The method comprises the following steps: introducing an 80-180 mg/mL beta-1,4-glycosidi
β-Glucosidases are a class of enzymes (EC: 3.2.1.21) that can hydrolyze the terminal, nonreducing β-D-glucosyl residues by hydrolyzing the β-1,4 glycosidic bond of various glycoconjugates including glucosides, oligosaccharides, and 1-O-glucosyl esters, to form glucose. ...
It is the polysaccharide composed of sugar monomers connected by cellotriose and fiber cellotetrose (namely 1, 2 and 1, 4 glycosidic bonds); The content ratio of (1, 3) glycosidic bond and (1, 4) glycosidic bond in β - glucan is 3: 7 Oat β- glucan solution - 1% quickly penetrate...
The cleaved-off different short molecules may undergo complete hydrolysis: ① acetyl xylan esterase removes the terminal acetate residues by break the ester linkage, α-D-glucuronidase attacks the α-1,2-glycosidic bond and releases the glucuronic acid side chain, and β-xylosidase hydrolyzes the ...
catalyzes the hydrolysis of the second alfa-1,4 glycosidic bond. Alternative names 1,4-alfa-D-glucan maltohydrolase,glycogenase,saccharogen. amylase). immunogen Beta amylase isolated and purified from sweet potato Q94EU9 antibody format rabbit polyclonal purified IgG in PBS lyophilized quantity 1 ...
by β-elimination reaction. The absorption peak at 825 cm−1pointed to an α-glycosidic bond while absorption at 893 cm−1was an sign of a β-glycosidic bond, although the bands at 930 cm−1, 1038 cm−1, 1078 cm−1, and 1161 cm−1also reflected β(1–3) ...
the class of carbohydrate derivatives. It is a white, crystalline powder that is highly soluble in organic solvents such as chloroform and acetone but insoluble in water. The compound is derived from maltose, a disaccharide composed of two glucose molecules linked by an a(1→4) glycosidic bond...
These molecules are exclusively linked by β-1,2 linkages and can be unsubstituted or decorated with phosphoglycerol, succinyl or malonyl moieties or a combination of them depending on the bacterial species. The absence of a reducing end and the type of glycosidic bond (β-1,2) turns the C...
Endo-β-N-acetylglucosaminidases (ENGases) are a class of glycoside hydrolases that hydrolyze the β-1,4-glycosidic bond in the N,N′-diacetylchitobiose core of N-glycans. The deglycosylation property of ENGases has been frequently used for structural and functional studies of glycoproteins. EN...
and capability of effectively guaranteeing specific glycosidic bond configurations. However, the enzymatic synthesis of LNT2 and LNnT mainly depends on activated artificial donors, such as p-nitrophenyl-β-N-acetylglucosaminide (pNP-GlcNAc) and uridine diphosphate-N-acetylglucosamine (UDP-GIcNAc). Activat...
