CAS Registry Number
Comments Chitin oligosaccharide deacetylase is a key enzyme in the chitin catabolic cascade of chitinolytic?Vibrio?strains. Besides being a nutrient, the heterodisaccharide product 4-O-(N-acetyl-¦Â-D-glucosaminyl)-D-glucosamine is a unique inducer of chitinase production in?Vibrio parahaemolyticus?[2]. In contrast to EC?3.5.1.41?(chitin deacetylase) this enzyme is specific for the chitin disaccharide [1,3]. It also deacetylates the chitin trisaccharide with lower efficiency [3]. No activity with higher polymers of GlcNAc [1,3].

History
Reactions N,N’-diacetylchitobiose + H(2)O = N-acetyl-beta-D-glucosaminyl-(1->4)-D- glucosamine + acetate.
