Folate metabolism pathway. Folate metabolites are in bold. Enzymes are in italics. The dashed line represents inhibition of the enzyme serine hydroxymethyltransferase by 5-formyl THF polyglutamate. THF = tetrahydrofolate, DHF = dihydrofolate, MTHFS = 5,10-methenyltetrahydrofolate synthetase, FGAR = formylglycinamide ribotide, GAR=glycinamide ribotide, AICAR = aminoimidazole carboxamide ribotide, FAICAR = formylaminoimidazole carboxamide ribotide, dTMP = deoxythmidine monophosphate, dUMP = deoxyuridine monophosphate.
