Then, it is reduced by DHF reductase (EC 1.5.1.3) to the biologically active cofactor tetrahydrofolate (THF) and subjected to the addition of multiple glutamate moieties by folylpolyglutamate synthase (EC 6.3.2.17) to yield THF-polyglutamate.

WebThe folate cycle starts with the conversion of dihydrofolate (DHF) to tetrahydrofolate (THF) through dihydrofolate reductase-thymidylate synthase (DHFR-TS) by using reducing equivalents from NADPH (nicotinamide adenine dinucleotide phosphate). Methyl groups gained from THFs (5,10-CH2-THF, 5,10-CH = THF) are synthesized by serine ... 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 ...
WebJan 7, 1999 · Folic acid is enzymatically reduced by dihydrofolate reductase (DHFR, EC 1.5.1.3) either partially to the intermediate dihydrofolate (DHF) or completely to tetrahydrofolate.
