Comments [?]

Function This enzyme is involved in nucleotide metabolism: it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA.
Catalytic activity RHEA:10248: dUTP + H2O = diphosphate + dUMP + H(+)
EC 3.6.1.23
Cofactor Mg(2+)
Pathway Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2.
case <OC:Escherichia> or <OC:Mycobacterium>
Subunit Homotrimer.
end case
Similarity Belongs to the dUTPase family.

Keywords [?]
