KEGG ENZYME: 3.2.1.132

ENZYME: 3.2.1.132

Entry

EC 3.2.1.132                Enzyme

Name

chitosanase

Class

Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds

Sysname

chitosan N-acetylglucosaminohydrolase

Reaction(IUBMB)

Endohydrolysis of beta-(1->4)-linkages between D-glucosamine residues in a partly acetylated chitosan

Reaction(KEGG)

(other) R02833 R06175(G)

Comment

A whole spectrum of chitosanases are now known (for more details, see {http://rbrzezinski.recherche.usherbrooke.ca/::http://rbrzezinski.recherche.usherbrooke.ca/}). They can hydrolyse 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 [4], 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.
