Summary

PYGB (glycogen phosphorylase B, HGNC:9723) is a protein-coding gene on chromosome 20p11.21, encoding Glycogen phosphorylase, brain form (P11216). Glycogen phosphorylase that regulates glycogen mobilization.

The protein encoded by this gene is a glycogen phosphorylase found predominantly in the brain. The encoded protein forms homodimers which can associate into homotetramers, the enzymatically active form of glycogen phosphorylase. The activity of this enzyme is positively regulated by AMP and negatively regulated by ATP, ADP, and glucose-6-phosphate. This enzyme catalyzes the rate-determining step in glycogen degradation.

Glycogen phosphorylase, brain formP11216 (reviewed: P11216)

All UniProt accessions (2): P11216, H0Y4Z6

UniProt curated annotations — full annotation on UniProt →

Function. Glycogen phosphorylase that regulates glycogen mobilization. Phosphorylase is an important allosteric enzyme in carbohydrate metabolism. Enzymes from different sources differ in their regulatory mechanisms and in their natural substrates. However, all known phosphorylases share catalytic and structural properties.

Subunit / interactions. Homodimer. Dimers associate into a tetramer to form the enzymatically active phosphorylase A.

Post-translational modifications. Phosphorylated. Phosphorylation of Ser-15 converts phosphorylase B (unphosphorylated) to phosphorylase A.

Activity regulation. Activity of phosphorylase is controlled both by allosteric means (through the non-covalent binding of metabolites) and by covalent modification. Thus AMP allosterically activates, whereas ATP, ADP, and glucose-6-phosphate allosterically inhibit, phosphorylase B. Activated upon phosphorylation.

Similarity. Belongs to the glycogen phosphorylase family.

PubChem BioAssay actives

11 with measured affinity, of 476 total; 8 most potent distinct compounds. Largely complementary to BindingDB; screening values are coarse (µM, 4 dp), so sub-nM hits tie at the floor.
