Thymidylate synthase

Gene

thyA

Organism
Parabacteroides distasonis (strain ATCC 8503 / DSM 20701 / CIP 104284 / JCM 5825 / NCTC 11152)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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
