FunFam 2644: 1D-myo-inositol 2-acetamido-2-deoxy-alpha-D-glucop...

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
N-acetyl-1-D-myo-inositol-2-amino-2-deoxy-alpha-D-glucopyranoside deacetylase. [EC: 3.5.1.103]
1-O-(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + H(2)O = 1-O-(2-amino-2-deoxy-alpha-D-glucopyranosyl)-1D-myo-inositol + acetate.
  • This enzyme is considered the key enzyme and rate limiting step in the mycothiol biosynthesis pathway.
  • In addition to acetylase activity, the enzyme possesses weak mycothiol conjugate amidase activity, and shares sequence similarity with mycothiol S-conjugate amidase.
  • Formerly EC 3.1.1.n1.

Chitin disaccharide deacetylase. [EC: 3.5.1.105]
N,N'-diacetylchitobiose + H(2)O = N-acetyl-beta-D-glucosaminyl-(1->4)-D- glucosamine + acetate.
  • 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.
