The phosphate groups are hydrolytically removed by phosphorylase phosphatase to form phosphorylase b and orthophosphate. Registry number: EC 2.4.1.- (12 Dec 1998) |
| phosphorylase b | <enzyme> The relatively inactive form of phosphorylase that is reactivated to form phosphorylase a by phosphorylase kinase, which catalyses the enzymatic phosphorylation of the serine residues at the expense of ATP. Registry number: EC 2.4.1.- (12 Dec 1998) |
| phosphorylase kinase | <enzyme> The enzyme that regulates the activity of phosphorylase and glycogen synthetase by addition of phosphate groups. A large and complex enzyme, itself regulated by phosphorylation. Integrates the hormonal and calcium signals in muscle. (18 Nov 1997) |
