UDP-L-Ara4N formyltransferase / UDP-GlcA C-4"-decarboxylase
10-Formyltetrahydrofolate → N5-Formyl-THF
Bifunctional purine biosynthesis protein ADE17
Phosphoribosylaminoimidazole carboxylase
S-Aminomethyldihydrolipoylprotein; + Tetrahydrofolic acid ↔ 5,10-Methylene-THF + Ammonia + dihydrolipoylprotein
10-Formyltetrahydrofolate + 4-Amino-4-deoxy-L-arabinose → Tetrahydrofolate + UDP-4-Deoxy-4-formamido-β-L-arabinose
L-Serine + Tetrahydrofolic acid ↔ 5,10-Methylene-THF + Glycine + Water
FAICAR + Tetrahydrofolic acid → 1-(5'-Phosphoribosyl)-5-amino-4-imidazolecarboxamide + 10-Formyltetrahydrofolate
5'-Phosphoribosyl-N-formylglycinamide + Tetrahydrofolic acid → 10-Formyltetrahydrofolate + Glycineamideribotide
Formic acid + Tetrahydrofolic acid → 10-Formyltetrahydrofolate + Water
N-formylmethionyl-tRNA(fMet) + Tetrahydrofolic acid ? 10-Formyltetrahydrofolate + L-Methionyl-tRNA(Met)
5'-phosphoribosyl-a-N-formylglycineamidine + Tetrahydrofolic acid → 5,10-Methenyltetrahydrofolic acid + Glycineamideribotide + Water
5,10-Methenyltetrahydrofolic acid + Water → N5-Formyl-THF
5,10-Methenyltetrahydrofolic acid + NADPH → 5,10-Methylene-THF + NADP
5-Methyltetrahydrofolic acid + Homocysteine → L-Methionine + Tetrahydrofolic acid
5-Thymidylic acid + Dihydrofolic acid → 5,10-Methylene-THF + dUMP
5,10-Methylene-THF + Hydrogen Ion + NADPH → 5-Methyltetrahydrofolic acid + NADP
Dihydrofolic acid + NADP → Folic acid + Hydrogen Ion + NADPH
Dihydrofolic acid + Hydrogen Ion + NADPH → NADP + Tetrahydrofolic acid
Folic acid + 2 Hydrogen Ion + 2 NADPH → 2 NADP + Tetrahydrofolic acid
10-Formyltetrahydrofolate + Hydrogen Ion ↔ 5,10-Methenyltetrahydrofolic acid + Water
