Glycoside hydrolases EC 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 glycoside hydrolases, based on sequence similarity, has led to the definition of >100 different families.[1][2][3] This classification is available on the CAZy web site,[4][5] and also discussed at CAZypedia, an online encyclopedia of carbohydrate active enzymes.[6][7]
Glycoside hydrolase family 59 CAZY GH_59 comprises enzymes with only one known activity; galactocerebrosidase (EC 3.2.1.46). Globoid cell leukodystrophy (Krabbe disease) is a severe, autosomal recessive disorder that results from deficiency of galactocerebrosidase (GALC) activity.[8][9][10] GALC is responsible for the lysosomal catabolism of certain galactolipids, including galactosylceramide and psychosine.[8]
