Glycosyl hydrolase enzymes hydrolyse the glycosidic bond
between two or more carbohydrates, or between a carbohydrate and a
non-carbohydrate moiety. This gene encodes a member of glycosyl
hydrolases family 31. This enzyme hydrolyses terminal, non-reducing
1,4-linked alpha-D-glucose residues and releases alpha-D-glucose.
This is a key enzyme in glycogen metabolism and its gene localizes
to a chromosomal region (15q15) that is associated with
susceptibility to diabetes.
