| Type: | Family | Name: | Glycoside hydrolase, family 39 |
| Description: | O-Glycosyl hydrolases () 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 [, ]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site.Glycoside hydrolase family 39 comprises enzymes with several known activities; alpha-L-iduronidase (); beta-xylosidase ().The most highly conserved regions in these enzymes are located in their N-terminal sections. These contain a glutamic acid residue which, on the basis ofsimilarities with other families of glycosyl hydrolases [], probably acts asthe proton donor in their catalytic mechanism. | Short Name: | Glyco_hydro_39 |
