Protein Domain : IPR004193

Name  Glycoside hydrolase, family 13, N-terminal Short Name  Glyco_hydro_13_N
Type  Domain Description  O-Glycosyl hydrolases () 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 [, ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.Enzymes containing this domain belong to family 13 () of the glycosyl hydrolases. This domain is found in a range of enzymes that act on branched substrates ie. isoamylase, pullulanase andbranching enzyme. Isoamylase hydrolyses 1,6-alpha-D-glucosidic branch linkages in glycogen, amylopectin anddextrin; 1,4-alpha-glucan branching enzyme functions in the formation of 1,6-glucosidic linkages of glycogen; andpullulanase is a starch-debranching enzyme.
