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:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616,
