Protein

Thymidylate synthase

Gene

thyA

Organism
Polaromonas sp. OV174
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the reductive methylation of 2'-deoxyuridine-5'-monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by-product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis.UniRule annotation

Catalytic activityi

5,10-methylenetetrahydrofolate + dUMP = dihydrofolate + dTMP.UniRule annotationSAAS annotation

Pathwayi: dTTP biosynthesis
