Structurally, functionally and mechanistically, bacte-rial and mammalian TSases share remarkable similarities. Because of this closeness, bac-terial enzymes have long been used as model systems for human TSase. Furthermore,

No redundancy exists in this pathway ...
WebbThymidylate kinase is a 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.

WebbThymidylate synthase plays a central role in the biosynthesis of thymidylate, an essential precursor for DNA biosynthesis. In addition to its role in catalysis and cellular … Thymidylate synthase (TS) (EC 2.1.1.45) is an enzyme that catalyzes the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP). Thymidine is one of the nucleotides in DNA. With inhibition of TS, an imbalance of deoxynucleotides and increased levels of dUMP arise. Both cause … Visa mer The following reaction is catalyzed by thymidylate synthase: 5,10-methylenetetrahydrofolate + dUMP $${\displaystyle \rightleftharpoons }$$ dihydrofolate + dTMP By means of reductive Visa mer The use of TS inhibitors has become a main focus of using TS as a drug target.
