Guanylate kinase

Guanylate kinase

In enzymology, a guanylate kinase is an enzyme that catalyzes the chemical reaction

ATP + GMP rightleftharpoons ADP + GDP

Thus, the two substrates of this enzyme are ATP and GMP, whereas its two products are ADP and GDP.

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with a phosphate group as acceptor. The systematic name of this enzyme class is ATP:(d)GMP phosphotransferase. Other names in common use include deoxyguanylate kinase, 5'-GMP kinase, GMP kinase, guanosine monophosphate kinase, and ATP:GMP phosphotransferase. This enzyme participates in purine metabolism.
