Family

Glycoside hydrolase, family 46 (IPR000400)

Short name: Glyco_hydro_46

Family relationships

None.

Description

O-Glycosyl hydrolases (EC: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 glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [PMID: 7624375, PMID: 8535779]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.

Glycoside hydrolase family 46 GH46 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 acetylated chitosan.
