Protein

Thymidylate synthase

Gene

thyA

Organism
Rhodopirellula baltica (strain DSM 10527 / NCIMB 13988 / SH1)
Status
Reviewed-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 annotation

Pathwayi: dTTP biosynthesis

This protein is involved in the pathway dTTP biosynthesis, which is part of Pyrimidine metabolism.UniRule annotation
View all proteins of this organism that are known to be involved in the pathway dTTP biosynthesis and in Pyrimidine metabolism.
