Enzyme Information

3.2.1.165

Exo-1,4-beta-D-glucosaminidase.

based on mapping to UniProt Q56F26

Hydrolysis of chitosan or chitosan oligosaccharides to remove successive D-glucosamine residues from the non-reducing termini.

-!- 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. -!- Can degrade GlcN-GlcNAc but not GlcNAc-GlcNAc.
