CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP +
CC carbamoyl phosphate + 2 H(+) + L-glutamate + phosphate;
CC Xref=Rhea:RHEA:18633, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:17544, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58228, ChEBI:CHEBI:58359,
CC ChEBI:CHEBI:456216; EC=6.3.5.5; Evidence={ECO:0000255|HAMAP-
CC Rule:MF_01209};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl
CC phosphate from bicarbonate: step 1/1. {ECO:0000255|HAMAP-
CC Rule:MF_01209}.
CC -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo pathway;
CC (S)-dihydroorotate from bicarbonate: step 1/3. {ECO:0000255|HAMAP-
CC Rule:MF_01209}.
CC -!- SUBUNIT: Composed of two chains; the small (or glutamine) chain
CC promotes the hydrolysis of glutamine to ammonia, which is used by the
CC large (or ammonia) chain to synthesize carbamoyl phosphate.
CC {ECO:0000255|HAMAP-Rule:MF_01209}.
CC -!- SIMILARITY: Belongs to the CarA family. {ECO:0000255|HAMAP-
CC Rule:MF_01209}.
