Webb29 okt. 2002 · In brief: 1-kb DNA fragments of the upstream and downstream regions of the E. coli thyA gene were PCR amplified from genomic DNA using primers: #EtAU5, #EtAU3, #EtAD5 and #EtAD3 (see Table 2 ). The DNA fragments were cloned into plasmid pCVD442 and used to transform E. coli MG1655 by electroporation. WebbThymidylate synthase (TS) ( EC 2.1.1.45) [5] 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 DNA damage. [6] [7] …
