phosphorylase phosphatase
1(phosphorylase) phosphatase — In enzymology, a [phosphorylase] phosphatase (EC number|3.1.3.17) is an enzyme that catalyzes the chemical reaction: [phosphorylase a] + 4 H2O ightleftharpoons 2 [phosphorylase b] + 4 phosphateThus, the two substrates of this enzyme are… …
2[phosphorylase] phosphatase — [phos·phor·y·lase] phos·pha·tase (fos forґə lās fosґfə tās″) [EC 3.1.3.17] an enzyme of the hydrolase class that catalyzes the cleavage of a phosphoryl group from (active) glycogen phosphorylase a to form (inactive)… …
