Overlapping homologous superfamilies

Family 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.

This entry represents proteins from Glycoside hydrolase family 15 and Phosphorylase b kinase regulatory chain family.

Glycoside hydrolase family 15 GH15 comprises enzymes with several known activities; glucoamylase (EC:; alpha-glucosidase (EC:; glucodextranase (EC:

Phosphorylase b kinase catalyzes the phosphorylation of serine in certain substrates, including troponin I. The alpha chain may bind calmodulin. The beta chain acts as a regulatory unit and modulates the activity of the holoenzyme in response to phosphorylation [PMID: 12825073].
