RT   "Complete sequence of chromosome 1 of Nocardioides sp. JS614.";
RL   Submitted (DEC-2006) to the EMBL/GenBank/DDBJ databases.
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}.
