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:456216; EC=6.3.5.5;
CC Evidence={ECO:0000256|ARBA:ARBA00001777};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + L-glutamine = L-glutamate + NH4(+);
CC Xref=Rhea:RHEA:15889, ChEBI:CHEBI:15377, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:58359;
CC Evidence={ECO:0000256|ARBA:ARBA00043737};
CC -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl
CC phosphate from bicarbonate: step 1/1. {ECO:0000256|ARBA:ARBA00005077}.
CC -!- SUBUNIT: Heterodimer composed of 2 chains; the small (or glutamine)
CC chain promotes the hydrolysis of glutamine to ammonia, which is used by
CC the large (or ammonia) chain to synthesize carbamoyl phosphate.
CC {ECO:0000256|ARBA:ARBA00044031}.
CC -!- SIMILARITY: Belongs to the CarA family.
CC {ECO:0000256|ARBA:ARBA00007800}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
