24 seconds: 5-Fluorouracil (5-FU) is a chemotherapy drug used to treat various cancers by inhibiting thymidylate synthetase (TS), essential for DNA synthesis. Our research focused on its mechanisms in wild-type and ThyA mutants of E. coli. We found that minimal thymidine is required for bacterial growth, and deoxyuridine inhibits ThyA mutants while enhancing 5-FU's effectiveness. Additionally, ThyA mutants needed less thymidine than CarAB.
