Overlapping entries


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.

Glycoside hydrolase family 3 GH3 comprises enzymes with a number of known activities; beta-glucosidase (EC:; beta-xylosidase (EC:; N-acetyl beta-glucosaminidase (EC:; glucan beta-1,3-glucosidase (EC:; cellodextrinase (EC:; exo-1,3-1,4-glucanase (EC:3.2.1). These enzymes are two-domain globular proteins that are N-glycosylated at three sites [PMID: 10368285]. This domain is often N-terminal to the glycoside hydrolase family 3, C-terminal domain IPR036881.
