Putative catalytic domain of uncharacterized bacterial hypothetical proteins similar to insect chitin deacetylase-like proteins
The family includes many uncharacterized bacterial hypothetical proteins that show high sequence similarity to insect chitin deacetylase-like proteins. Chitin deacetylases (CDAs, EC 3.5.1.41) are secreted metalloproteins belonging to a family of extracellular chitin-modifying enzymes that catalyze the N-deacetylation of chitin, a beta-1,4-linked N-acetylglucosamine polymer, to form chitosan, a polymer of beta-(1,4)-linked d-glucosamine residues.
