Protein

Bifunctional dihydrofolate reductase-thymidylate synthase

Gene
N/A
Organism
Plasmodium falciparum (isolate K1 / Thailand)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Bifunctional enzyme. Involved in de novo dTMP biosynthesis. Key enzyme in folate metabolism. Catalyzes an essential reaction for de novo glycine and purine synthesis, DNA precursor synthesis, and for the conversion of dUMP to dTMP.

Catalytic activityi

5,6,7,8-tetrahydrofolate + NADP+ = 7,8-dihydrofolate + NADPH.
5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.
