Enzyme reactions

• Enzyme class: E.C.1.5.1.3 - dihydrofolate reductase.
• Pathway: Folate Coenzymes
• Reaction: (6S)-5,6,7,8-tetrahydrofolate + NADP⁺ = 7,8-dihydrofolate + NADPH + H⁺

(6S)-5,6,7,8-tetrahydrofolate + NADP(+) (Bound ligand (Het Group name = NDP) corresponds exactly) = 7,8-dihydrofolate (Bound ligand (Het Group name = FOL) corresponds exactly) + NADPH + H(+)
