In enzymology, a guanylate kinase (EC 188.8.131.52) is an enzyme that catalyzes the chemical reaction:ATP + GMP↔ 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. This enzyme participates in purine metabolism.
