Webb1 dec. 2002 · T hymidylate synthase (TS) is necessary for the de novo synthesis of DNA in proliferating cells, catalyzing the methylation of deoxyuridine monophosphate to thymidine monophosphate ( Danenberg 1977 ). 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 … 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. The most widely used inhibitor is 5-fluorouracil (5-FU), which acts as an antimetabolite that irreversibly inhibits TS by competitive binding. However, due to a low level of 5-FU … Visa mer In the proposed mechanism, TS forms a covalent bond to the substrate dUMP through a 1,4-addition involving a cysteine nucleophile.
