A new class EC 7, Translocases, has been added to the EC list. It will be part of ENZYME from release 2018_10. Read more about EC 7 here.
ENZYME entry: 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.
