CC -!- FUNCTION: Catalyzes the ATP-dependent amination of UTP to CTP with
CC either L-glutamine or ammonia as the source of nitrogen.
CC {ECO:0000256|RuleBase:RU810713}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O + L-glutamine + UTP = ADP + CTP + 2 H(+) + L-
CC glutamate + phosphate; Xref=Rhea:RHEA:26426, ChEBI:CHEBI:15377,

CC ChEBI:CHEBI:58359, ChEBI:CHEBI:456216; EC=6.3.4.2;
CC Evidence={ECO:0000256|ARBA:ARBA00000314,
CC ECO:0000256|RuleBase:RU810713};
CC -!- PATHWAY: Pyrimidine metabolism; CTP biosynthesis via de novo pathway;
CC CTP from UDP: step 2/2. {ECO:0000256|ARBA:ARBA00005171,
CC ECO:0000256|RuleBase:RU810713}.
CC -!- SIMILARITY: Belongs to the CTP synthase family.
CC {ECO:0000256|ARBA:ARBA00007533, ECO:0000256|RuleBase:RU810713}.
