| glycogen phosphorylase |
<enzyme> Enzyme that catalyses the sequential removal of glycosyl residues from glycogen to yield one glucose-1-phosphate per reaction. Its activity is controlled by phosphorylation (by phosphorylase kinase).
(21 Jun 2000) |
| phosphorylase |
<enzyme> Enzyme that catalyses the sequential removal of glycosyl residues from glycogen to yield one glucose-1-phosphate per reaction. Its activity is controlled by phosphorylation (by phosphorylase kinase).
(21 Jun 2000) |
| phosphorylase a |
<enzyme> The phosphorylated and more active form of phosphorylase that functions as a regulatory enzyme during glycogen breakdown. 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) |
| phosphorylase kinase phosphatase |
<enzyme> Aspect of phosphoprotein phosphatase EC 3.1.3.16
Registry number: EC 3.1.3.-
(26 Jun 1999) |
| phosphorylase phosphatase |
<enzyme> An enzyme that deactivates glycogen phosphorylase a by releasing inorganic phosphate and phosphorylase b, the inactive form.
Chemical name: (Phosphorylase a) phosphohydrolase
Registry number: EC 3.1.3.17
(12 Dec 1998) |
| phosphorylase-rupturing enzyme |
