Protein Domain : IPR011837

Name  Glycogen debranching enzyme, GlgX type Short Name  Glycogen_debranch_GlgX
Type  Family 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.This entry represents the glycogen debranching enzyme GlgX found in Escherichia coli, as well as its equivalogs in other prokaryotic species. This enzyme encodes an isoamylase-type debranching enzyme with high specificity for hydrolysis of chains consisting of three or four glucose residues, and is classed as family 13 of glycosyl hydrolases []. GlgX is not required for glycogen biosynthesis, but instead acts as a debranching enzyme for glycogen catabolism. This entry distinguishes GlgX from pullanases and other related proteins that also operate on alpha-1,6-glycosidic linkages [].
