This article is about the database. For the community in the United States, see Cazy, West Virginia.

CAZy is a database of Carbohydrate-Active enZYmes.[1] This database contains a classification and associated information about enyzmes involved in the synthesis, metabolism, and transport of carbohydrates. Included in this database are glycoside hydrolases, glycosyltransferases, polysaccharide lyases, carbohydrate esterase and carbohydrate-binding families.


CAZy identifies evolutionary related families of glycosyl hydrolases using the classification introduced by Bernard Henrissat.[2][3] As of 2012 CAZy contains 131 families of glycosyl hydrolase families. These families are given a number to identify them, so for example Glycosyl hydrolase family 1 contains enzymes that possess a TIM barrel fold. These families are clustered into 14 different clans that share structural similarity. CAZy contains 94 families of Glycosyl transferase enzymes,[4] 22 families of polysaccharide lysases[5] and 16 families of carbohydrate esterases.
