(phosphorylase) phosphatase

In enzymology, a [phosphorylase] phosphatase is an enzyme that catalyzes the chemical reaction


 * [phosphorylase a] + 4 H2O $$\rightleftharpoons$$ 2 [phosphorylase b] + 4 phosphate

Thus, the two substrates of this enzyme are [phosphorylase a] and H2O, whereas its two products are [phosphorylase b] and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is [phosphorylase a] phosphohydrolase. Other names in common use include PR-enzyme, phosphorylase a phosphatase, glycogen phosphorylase phosphatase, protein phosphatase C, and type 1 protein phosphatase.
