Glycoside hydrolasesEC 3.2.1. are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families.[1][2][3] This classification is available on the CAZy web site,[4][5] and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.[6][7]
Glycoside hydrolase family 46 CAZY GH_46 comprises enzymes with only one known activity; chitosanase (EC 3.2.1.132). Chitosanase enzymes catalyse the endohydrolysis of beta-1,4-linkages between N-acetyl-D-glucosamine and D-glucosamine residues in a partly acetylatedchitosan.
