Gene Family: Glycogen phosphorylases (PYG)

Also known as : "Phosphorylases, glycogen"
A subset of : Glycosyltransferases

Glycogen phosphorylase: Glycogen phosphorylase is one of the phosphorylase enzymes ( EC 2.4.1.1 ). Glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis in animals by releasing glucose-1-phosphate from the terminal alpha-1,4-glycosidic bond. Glycogen phosphorylase is also studied as a model protein regulated by both reversible phosphorylation and allosteric effects. [Source: Wikipedia]
