Chitosanase and Chitosan

Chitosanase
EC# 3.2.1.132
Synonyms: chitosan N-acetylglucosaminohydrolase
Chitosanase catalyzes the endohydrolysis of β-1,4-linkages between D-glucosamine (GlcN-GlcN) residues in chitosan. The enzyme from Streptomyces has been reported to also hydrolyze the GlcNAc-GlcN linkage in partially acetylated chitosan.
