Glycoside hydrolase family 31
In molecular biology, glycoside hydrolase family 31 is a family of glycoside hydrolases.
Glycoside 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 glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families. This classification is available on the CAZy web site, and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.
Glycoside hydrolase family 31 comprises enzymes with several known activities; alpha-glucosidase, alpha-galactosidase ; glucoamylase, sucrase-isomaltase ; alpha-xylosidase ; alpha-glucan lyase.
Glycoside hydrolase family 31 groups a number of glycosyl hydrolases on the basis of sequence similarities An aspartic acid has been implicated in the catalytic activity of sucrase, isomaltase, and lysosomal alpha-glucosidase.
