Chitosanase.
based on mapping to UniProt P33673
Endohydrolysis of beta-(1->4)-linkages between D-glucosamine residues in a partly acetylated chitosan.
-!- 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.
