应用

Diacetylchitobiose/Chitobiose, a dimer of β(1,4) linked N-acetyl-D glucosamine, is used as an alternative source of N-acetylglucosamine by some bacteria. It is used in fermentation research to study, differentiate and characterize chitobiose transporter systems and enzymes such as β-N-acetylglucosaminidase(s) and chitobiose phosphorylase(s).

生化/生理作用

In chitinolytic bacteria, such as Vibrio, Streptomyces and Serratia, N,N′-Diacetylchitobiose (GlcNAc2) is not only a major breakdown product of chitinase, but it is also the smallest substance that induces chitinase production. It can also be utilized as a carbon source by E. coli, which does not express chitinases, but is exposed to GlcNAc2 produced by intestinal chitinolytic bacteria. In most organisms, the uptake of GlcNAc2 occurs via the phosphoenolpyruvate:glycose phosphotransferase system (PTS). GlcNAc2 has also been used as a substrate or inhibitor to study the activity of glycolytic enzymes.

The chitinolytic enzyme machinery of fungi consists of chitinases and beta-N-acetylglucosaminidases. These enzymes are important during the fungal life cycle for degradation of exogenous chitin, which is the second most abundant biopolymer, as well as fungal cell-wall remodelling. In addition

The linkage region, GlcNAcβAsn, is conserved in all eukaryotic N-glycoproteins. As a logical extension of a research endeavor aimed at understanding the structural significance of GlcNAc and Asn as the linkage region constituents, the newer analogs GlcNAcβNHBu and (GlcNAcβ(1-4)GlcNAc)alkanamides have

There is no structural information about any chitinase synthesized by Bacillus thuringiensis, the most successful microbial insect larvicide used worldwide. In this study, we solved the 3D structure of the chitinase ChiA74 at 2.26 Å. The crystal structure shows that ChiA74

Lytic polysaccharide monooxygenases (LPMOs) represent a recent addition to the carbohydrate-active enzymes and are classified as auxiliary activity (AA) families 9, 10, 11, and 13. LPMOs are crucial for effective degradation of recalcitrant polysaccharides like cellulose or chitin. These enzymes

Chitin, one of Nature's most abundant biopolymers, can be obtained by either traditional chemical pulping or by extraction using the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate. The IL extraction and coagulation process provides access to a unique chitin, with an open
