Chemical synthesis of the Plasmodium falciparum dihydrofolate reductase-thymidylate synthase gene.
Plasmodium falciparum dihydrofolate reductase-thymidylate synthase (DHFR-TS) is a well-known target for pyrimethamine and cycloguanil. The low amounts of enzyme obtainable from parasites or the currently available heterologous expression systems have thus far hindered studies of this enzyme. The 1912-base pair P. falciparum DHFR-TS gene was designed based on E. coli codon preference with unique...
متن کاملNovel chemical strategies for thymidylate synthase inhibition.
Thymidylate synthase (TS) is a well-validated target for cancer chemotherapy. TS was established as the principal target of the widely used anticancer drug 5-fluorouracil (5FU). The 5FU metabolite FdUMP forms a covalent complex with TS that is stabilized by 5-formyl tetrahydrofolate (leucovorin; LV). Numerous chemical strategies have been employed to develop novel TS inhibitors that are superio...
متن کاملInvestigation on chemical steps of thymidylate synthase catalyzed reaction
Thymidylate synthase (TS) catalyzes the reductive methylation of 2’deoxyuridylate (dUMP) with cofactor 5,10-methylene-5, 6, 7, 8-tetrahydrofolate, forming thymidine monophosphate (dTMP) and 7, 8-dihydrofolate. The reaction pathway is comprised of at least seven covalent bond cleavage or formation, therefore, it is a very complex system for scientists to explore the mechanistic details of this r...
متن کاملIsolation and expression of the Pneumocystis carinii thymidylate synthase gene.
The thymidylate synthase (TS) gene from Pneumocystis carinii has been isolated from complementary and genomic DNA libraries and expressed in Escherichia coli. The coding sequence of TS is 891 nucleotides, encoding a 297-amino acid protein of Mr 34,269. The deduced amino acid sequence is similar to TS from other organisms and is most closely related to the enzyme from Saccharomyces cerevisiae wi...
متن کاملBidirectional promoter of the mouse thymidylate synthase gene.
The promoter of the mouse thymidylate synthase (TS) gene lacks both a TATAA box and an initiator element and directs transcriptional initiation at multiple sites over a 90 nucleotide initiation window. Earlier studies defined an essential region near the 5' end of the initiation window that is required for promoter activity. The essential region contains possible binding sites for Sp1 and Ets t...
