IUBMB Comments
Chitosan is a partially or totally N-deacetylated chitin derivative that is found in the cell walls of some phytopathogenic fungi and comprises D-glucosamine residues with a variable content of GlcNAc residues . Acts specifically on chitooligosaccharides and chitosan, having maximal activity on chitotetraose, chitopentaose and their corresponding alcohols . The enzyme can degrade GlcN-GlcNAc but not GlcNAc-GlcNAc . A member of the glycoside hydrolase family 2 (GH-2) .
