WebDihydrofolate Reductase (DHFR) Dihydrofolate reductase is an enzyme that converts dihydrofolate to tetrahydrofolate and is involved in purines and thymidylate synthesis. It is encoded by the human DHFR gene. Antifolate drugs, methotrexate (MTX) and trimetrexate, can tightly bind to DHFR and inhibit DNA synthesis and cell proliferation. WebJun 9, 2024 · Dihydrofolate reductase (DHFR-1) carries out the first two reaction steps, reducing folic acid to dihydrofolic acid (DHF) and on to tetrahydrofolate (THF) (Fig. 1d). Using serine as a methyl donor ...
