ENZYME entry: EC 3.5.1.105

PURL: https://purl.expasy.org/enzyme/EC/3.5.1.105
Accepted Name
chitin disaccharide deacetylase
Alternative Name(s)
chitin oligosaccharide amidohydolase
chitin oligosaccharide deacetylase
chitobiose amidohydolase
Reaction catalysed
N,N'-diacetylchitobiose + H2O = N-acetyl-beta-D-glucosaminyl-(1->4)-D-glucosamine + acetate
Comment(s)
  • 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-beta-D-glucosaminyl)-D-glucosamine is a unique inducer of chitinase production in Vibrio parahemolyticus.
  • In contrast to EC 3.5.1.41 this enzyme is specific for the chitin disaccharide.
  • It also deacetylates the chitin trisaccharide with lower efficiency.
  • No activity with higher polymers of GlcNAc.
