O-Glycosyl hydrolases (3.2.1.) 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 85 different families [1, 2]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.

Glycoside hydrolase family 38 GH38 comprises enzymes with only one known activity; alpha-mannosidase (3.2.1.24) (3.2.1.114). This domain is found at the C terminus of glycosyl hydrolases from family 38.
