| 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 3 comprises enzymes with a number of known activities; beta-glucosidase (); beta-xylosidase (); N-acetyl beta-glucosaminidase (); glucan beta-1,3-glucosidase (); cellodextrinase (); exo-1,3-1,4-glucanase (). These enzymes are two-domain globular proteins that are N-glycosylated at three sites []. This domain is oftenN-terminal to the glycoside hydrolase family 3, C-terminal domain . The signature pattern in these enzymes is centred on a conserved aspartic acid residue which has been shown [], in Aspergillus wentiibeta-glucosidase A3, to be implicated in the catalytic mechanism. | Short Name: | Glyco_hydro_3_AS |
