Thymidylate kinase ( TMPK ) is a key enzyme for pyrimidine synthesis that catalyzes the phosphorylation of thymidine 5 ' - monophosphate ( dTMP ) in the presence of ATP and Mg ( 2 + ) to form thymidine 5 ' - diphosphate ( dTDP ) , which is then converted to thymidine 5 ' - triphosphate ( dTTP ) by nucleoside - diphosphate kinase ( NDK ) .
