ENZYME entry: EC 3.2.1.165

Accepted Name
exo-1,4-beta-D-glucosaminidase
Alternative Name(s)
exo-beta-D-glucosaminidase
exochitosanase
GlcNase
Reaction catalysed
Hydrolysis of chitosan or chitosan oligosaccharides to remove successive D-glucosamine residues from the non-reducing termini
Comment(s)
  • 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.
