Glycoside 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 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 31 CAZY GH_31 comprises enzymes with several known activities; alpha-glucosidase (EC 3.2.1.20), alpha-galactosidase (EC 3.2.1.22); glucoamylase (EC 3.2.1.3), sucrase-isomaltase (EC 3.2.1.48) (EC 3.2.1.10); alpha-xylosidase (EC 3.2.1); alpha-glucan lyase (EC 4.2.2.13).
Glycoside hydrolase family 31 groups a number of glycosyl hydrolases on the basis of sequence similarities[8][9][10] An aspartic acid has been implicated[11] in the catalytic activity of sucrase, isomaltase, and lysosomal alpha-glucosidase.
