Chitosanase (EC 3.2.1.132) is an enzyme with systematic name chitosan N-acetylglucosaminohydrolase. ^{[1] [2] [3] [4]} This enzyme catalyses the following chemical reaction

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

A whole spectrum of chitosanases are known.
