UniProtKB - F7QVL3 (F7QVL3_9LACO)
Protein
Thymidylate synthase
Gene
thyA
Organism
Lactobacillus salivarius GJ-24
Status
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
Caution
Lacks conserved residue(s) required for the propagation of feature annotation.UniRule annotation
The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.Imported
