Domain relationships


O-Glycosyl 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 glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [PMID: 7624375, PMID: 8535779]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.

Members of this family belong to the chitinase class II group which includes chitinase, chitodextrinase and the killer toxin of Kluyveromyces lactis (Yeast) (Candida sphaerica) and all belong to glycoside hydrolase, family 18 GH18. The chitinases hydrolyse chitin oligosaccharides. However, glycoside hydrolase family 18 also includes chitinase-like proteins, which bind but do not cleave chitin [PMID: 22550243].
