Description | O-Glycosyl 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 glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [, ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) website.Glycoside hydrolase family 2 comprises enzymes with several known activities; beta-galactosidase (); beta-mannosidase ( ); beta-glucuronidase ( ). 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. Beta-galactosidase from E. coli has a TIM-barrel-like core surrounded by four other largely beta domains [ ]. |
