FunFam 449: Chitosanase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Chitosanase. [EC:]
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.
