2.4.1.16 N-acetyl-D-glucosamine GlcNAc and 2-acylamido analogues of GlcNAc stimulate formation of chitin oligosaccharides by yeast chitin synthase, and GlcNAc is transferred to the 2-acylamido analogues. Synthesis of chitin oligosaccharides is strongly dependent on inclusion of GlcNAc in chitin synthase incubations. Formation of both chitin oligosaccharides and insoluble chitin is also stimulated by GlcNAc2 Saccharomyces cerevisiae

Synthesis of chitin oligosaccharides is strongly dependent on inclusion of GlcNAc in chitin synthase incubations, and N,N'-diacetylchitobiose is the major reaction product.

General Information

EC Number General Information Comment Organism
2.4.1.16 physiological function chitin synthases transfer GlcNAc from UDP-GlcNAc to preexisting chitin chains in reactions that are typically stimulated by free GlcNAc. The enzyme is involved in biosynthesis of chitin, a homopolymer of beta-1,4-linked GlcNAc residues and a key component of fungal cell walls and the arthropod exoskeleton Saccharomyces cerevisiae
