General annotation (Comments)

Function

Bifunctional enzyme. Involved in de novo dTMP biosynthesis. Key enzyme in folate metabolism. Can play two different roles depending on the source of dihydrofolate: de novo synthesis of tetrahydrofolate or recycling of the dihydrofolate released as one of the end products of the TS catalyzed reaction. Catalyzes an essential reaction for de novo glycine and purine synthesis, DNA precursor synthesis, and for the conversion of dUMP to dTMP.

Catalytic activity

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

5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.

Pathway

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

Subunit structure

Heterodimer or homodimer By similarity.

Sequence similarities

In the N-terminal section; belongs to the dihydrofolate reductase family.

In the C-terminal section; belongs to the thymidylate synthase family.

Contains 1 DHFR (dihydrofolate reductase) domain.

Sequence caution

The sequence AAA32789.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAA18836.1 differs from that shown. Reason: Erroneous gene model prediction.

The sequence CAB80174.1 differs from that shown. Reason: Erroneous gene model prediction.
