5,10-methylene-5,6,7,8-tetrahydrofolate + dUMP
7,8-dihydrofolate + dTMP
show the reaction diagram
thymidylate synthase is the third enzyme in the methylene tetrahydrofolate cycle besides dihydrofolate reductase and serine hydroxymethyltransferase, in many organisms, thymidylate synthase is the only de novo source for dTMP required for DNA synthesis
