CC   -!- FUNCTION: This enzyme is involved in nucleotide metabolism: it produces
CC       dUMP, the immediate precursor of thymidine nucleotides and it decreases
CC       the intracellular concentration of dUTP so that uracil cannot be
CC       incorporated into DNA. {ECO:0000250|UniProtKB:P17374}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=dUTP + H2O = diphosphate + dUMP + H(+); Xref=Rhea:RHEA:10248,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:61555, ChEBI:CHEBI:246422; EC=3.6.1.23;
CC         Evidence={ECO:0000250|UniProtKB:P17374};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:10249;
CC         Evidence={ECO:0000250|UniProtKB:P17374};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC   -!- INDUCTION: Expressed in the early phase of the viral replicative cycle.
CC       {ECO:0000250|UniProtKB:P17374}.
CC   -!- SIMILARITY: Belongs to the dUTPase family. {ECO:0000305}.
CC   -!- CAUTION: Was originally thought to be a protease-like protein
CC       (pseudoprotease). {ECO:0000305}.
