# List of glycoside hydrolase families

Glycoside hydrolases (O-Glycosyl hydrolases) EC3.2.1. 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 numerous different families. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site. Because the fold of proteins is better conserved than their sequences, some of the families can be grouped in 'clans'. As of October 2011, CAZy includes 128 families of glycosyl hydrolases and 14 clans.
