 In molecular biology, Glycoside hydrolase family 2 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.〔(Bairoch, A. "Classification of glycosyl hydrolase families and index of glycosyl hydrolase entries in SWISS-PROT". 1999. )〕 This classification is available on the CAZy(http://www.cazy.org/GH1.html) web site,〔(Henrissat, B. and Coutinho P.M.  "Carbohydrate-Active Enzymes server". 1999. )〕 and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.〔(CAZypedia, an online encyclopedia of carbohydrate-active enzymes. )〕
 Glycoside hydrolase family 2 comprises enzymes with several known activities: beta-galactosidase (EC 3.2.1.23); beta-mannosidase (EC 3.2.1.25); beta-glucuronidase (EC 3.2.1.31). These enzymes contain a conserved glutamic acid residue which has been shown, in ''Escherichia coli'' lacZ (), to be the general acid/base catalyst in the active site of the enzyme.
 The catalytic domain of Beta-galactosidases  have a TIM barrel core surrounded several other largely beta domains. The sugar binding domain of these proteins has a jelly-roll fold.〔 These enzymes also include an immunoglobulin-like beta-sandwich domain.〔
