Exo-1,4-beta-D-glucosaminidase (EC 3.2.1.165, CsxA, GlcNase, exochitosanase, GlmA, exo-beta-D-glucosaminidase, chitosan exo-1,4-beta-D-glucosaminidase) is an enzyme with system name chitosan exo-(1->4)-beta-D-glucosaminidase.[1][2][3][4][5] This enzyme catalyses the following chemical reaction
- 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 .
