General annotation (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 By similarity. HAMAP-Rule MF_00116

Catalytic activity

dUTP + H2O = dUMP + diphosphate. HAMAP-Rule MF_00116

Cofactor

Magnesium By similarity. HAMAP-Rule MF_00116

Pathway

Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP route): step 2/2. HAMAP-Rule MF_00116

Sequence similarities

Belongs to the dUTPase family.
