CC -!- FUNCTION: Catalyzes the deamination of dCTP to dUTP.
CC {ECO:0000256|HAMAP-Rule:MF_00146}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=dCTP + H(+) + H2O = dUTP + NH4(+); Xref=Rhea:RHEA:22680,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:61481, ChEBI:CHEBI:61555; EC=3.5.4.13;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00146};
CC -!- PATHWAY: Pyrimidine metabolism; dUMP biosynthesis; dUMP from dCTP (dUTP
CC route): step 1/2. {ECO:0000256|HAMAP-Rule:MF_00146}.
CC -!- SUBUNIT: Homotrimer. {ECO:0000256|HAMAP-Rule:MF_00146}.
CC -!- SIMILARITY: Belongs to the dCTP deaminase family. {ECO:0000256|HAMAP-
CC Rule:MF_00146}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00146}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
