General annotation (Comments)

Function

Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis By similarity.

Catalytic activity

5,6,7,8-tetrahydrofolate + NADP+ = 7,8-dihydrofolate + NADPH.

Pathway

Cofactor biosynthesis; tetrahydrofolate biosynthesis; 5,6,7,8-tetrahydrofolate from 7,8-dihydrofolate: step 1/1.

Subunit structure

Homodimer By similarity.

Miscellaneous

Confers high-level trimethoprim resistance.

Sequence similarities

Belongs to the dihydrofolate reductase family.

Contains 1 DHFR (dihydrofolate reductase) domain.
