CC -!- FUNCTION: Bifunctional enzyme that catalyzes both the deamination of
CC dCTP to dUTP and the hydrolysis of dUTP to dUMP without releasing the
CC toxic dUTP intermediate. {ECO:0000255|HAMAP-Rule:MF_00146}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=dCTP + 2 H2O = diphosphate + dUMP + NH4(+);
CC Xref=Rhea:RHEA:19205, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:61481, ChEBI:CHEBI:246422;
CC EC=3.5.4.30; Evidence={ECO:0000255|HAMAP-Rule:MF_00146};
CC -!- PATHWAY: Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP: step
CC 1/1. {ECO:0000255|HAMAP-Rule:MF_00146}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_00146}.
CC -!- SIMILARITY: Belongs to the dCTP deaminase family. {ECO:0000255|HAMAP-
CC Rule:MF_00146}.
