WebThe Folate cycle begins with the conversion of dietary folate (vitamin B9) into dihydrofolate (DHF) then tetrahydrofolate (THF) by dihydrofolate reductase (DHFR). Next, tetrahydrofolate (THF) is converted to 5, 10-methylene-THF by serine hydroxymethyltransferase (SHMT) before being reduced into 5-methyl-THF (5-mTHF) by methylenetetrahydrofolate ... WebDec 1, 2015 · DHFR is a key enzyme in folate metabolism as it is involved in 5,10-methylene tetra hydro folate (THF) generation from 7,8-dihydrofolate (DHF).
