Glycoside hydrolase family 1 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 1 CAZY GH_1 comprises enzymes with a number of known activities; beta-glucosidase (); beta-galactosidase (); 6-phospho-beta-galactosidase (); 6-phospho-beta-glucosidase (); lactase-phlorizin hydrolase (), lactase (); beta-mannosidase (); myrosinase ().
