In enzymology, a dTMP kinase (EC 2.7.4.9) is an enzyme that catalyzes the chemical reaction: ATP + dTMP rightleftharpoons ADP + dTDP. Thus, the two substrates of this enzyme are ATP and dTMP, whereas its two products are ADP and dTDP. 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 pyrimidine metabolism.
