CC   -!- FUNCTION: Involved in nucleotide metabolism: produces dUMP, the
CC       immediate precursor of thymidine nucleotides and decreases the
CC       intracellular concentration of dUTP to avoid uracil incorporation into
CC       viral DNA. {ECO:0000255|HAMAP-Rule:MF_04031}.
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         Evidence={ECO:0000255|HAMAP-Rule:MF_04031};
CC   -!- SIMILARITY: Belongs to the dUTPase family. {ECO:0000255|HAMAP-
CC       Rule:MF_04031}.
