Thus, it is of great significance to discover a 尾-N-acetyl glucosaminidase (NAGase) that can not only produce GlcNAc, but also synthesize N-Acetyl COSs. Results: The gene encoding the novel 尾-N-acetyl glucosaminidase, designated CmNAGase, was cloned from Chitinolyticbacter meiyuanensis SYBC...
Endochitinases (EC 3.2.1.14) randomly catalyze the cleavage of β-1,4-glycosidic bonds in chitin to release N-acetyl chitooligosaccharides (N-acetyl COSs); exochitinases (EC 3.2.1.52) can be divided into two subcategories: chitobiosidases (EC 3.2.1.29), which catalyze the successive release...
Background: N-Acetyl glucosamine (GlcNAc) and N-Acetyl chitooligosaccharides (N-Acetyl COSs) exhibit many biological activities, and have been widely used ... A Zhang,X Mo,N Zhou,... - 《Biotechnology for Biofuels》 被引量: 0发表: 2020年 ...
Analysis of the hydrolysis products of N-acetyl chitin oligosaccharides (N-Acetyl COSs) indicated that NAGaseA was capable of converting N-acetyl COSs ((GlcNAc)2–(GlcNAc)6) into GlcNAc with hydrolysis ability order: (GlcNAc)2 > (GlcNAc)3 > (GlcNAc)4 > (GlcNAc)5 > (GlcNAc)6. Moreover...
Chitinases play important role in chitin bioconversion, while few of them have been put into use due to their poor properties. We aimed to identify and characterize chitinases suitable for N -acetyl chitooligosaccharides (COSs) production from chitin materials.A chitinase gene ( SsChi28 ) from ...
BsPdaC contains a C-terminal family 4 carbohydrate esterase (CE4) catalytic domain, but unlike other MurNAc deacetylases, BsPdaC also has GlcNAc deacetylase activity on chitooligosaccharides (COSs), characteristic of chitin deacetylases. To uncover the molecular basis of this dual activity, here we ...
