Comments

CATALYTIC ACTIVITY: 5,6,7,8-tetrahydrofolate + NADP⁺ = 7,8-dihydrofolate + NADPH.
CATALYTIC ACTIVITY: 5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.
PATHWAY: Cofactor biosynthesis; tetrahydrofolate biosynthesis; tetrahydrofolate from dihydrofolate: step 1/1 .
MISCELLANEOUS: The reaction catalyzed by this enzyme represents an essential step for de novo glycine and purine synthesis, DNA precursor synthesis, and for the conversion of dUMP to dTMP.
SIMILARITY: In the N-terminal section; belongs to the dihydrofolate reductase family.
SIMILARITY: In the C-terminal section; belongs to the thymidylate synthase family.
SIMILARITY: Contains 1 DHFR (dihydrofolate reductase) domain.
