ENZYME entry: EC 3.2.1.132

PURL: https://purl.expasy.org/enzyme/EC/3.2.1.132
Accepted Name
chitosanase
Reaction catalysed
Endohydrolysis of beta-(1->4)-linkages between D-glucosamine residues in a partly acetylated chitosan
Comment(s)
  • A whole spectrum of chitosanases are now known that can hydrolyze various types of links in chitosan.
  • The only constant property is the endohydrolysis of GlcN-GlcN links, which is common to all known chitosanases.
  • One known chitosanase is limited to this link recognition, while the majority can also recognize GlcN-GlcNAc links or GlcNAc-GlcN links but not both.
  • They also do not recognize GlcNAc-GlcNAc links in partly acetylated chitosan.
