Protein Domain : Thymidylate kinase, conserved site IPR018095

Description	Thymidylate kinase ( ; dTMP kinase) catalyses the phosphorylation of thymidine 5'-monophosphate (dTMP) to form thymidine 5'-diphosphate (dTDP) in the presence of ATP and magnesium: ATP + thymidine 5'-phosphate = ADP + thymidine 5'-diphosphate Thymidylate kinase is an ubiquitous enzyme of about 25 Kd and is important in the dTTP synthesis pathway for DNA synthesis. The function of dTMP kinase in eukaryotes comes from the study of a cell cycle mutant, cdc8, in Saccharomyces cerevisiae. Structural and functional analyses suggest that the cDNA codes for authentic human dTMP kinase. The mRNA levels and enzyme activities corresponded to cell cycle progression and cell growth stages [ ].
