UniProtKB description: Involved in nucleotide metabolism: produces dUMP, the immediate precursor of thymidine nucleotides and decreases the intracellular concentration of dUTP, so that uracil cannot be incorporated into DNA (PubMed:9679200). The Ser-62 side chain changes its position upon ligand-binding to make contacts with the nucleotide phosphates (PubMed:21358047).
