Dhf folato
WebDHF was produced by reduction of folate as described by Blakley.19NADPH was obtained from Alexis Biochemicals. Concentrations of DHF and NADPH were measured using their respective extinction coefficients, 7.75 × 103and 6.22 × 103M−1cm at 340 nm.20For the reaction, the extinction coefficient was 12.3 × 103mol−1cm−1.21 WebTwo folate synthesis mutants, with respective dihydrofolate synthase (DHFS) and dihydropteroate synthase (DHPS) deletions and requiring DHF for growth were exposed to sulfa drugs. The DHFS knockout mutant was inhibited, but the DHPS knockout mutant that was incapable of forming sulfa-DHP was insensitive.
