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.
