CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 ATP + H2O + hydrogencarbonate + L-glutamine = 2 ADP +
CC         carbamoyl phosphate + 2 H(+) + L-glutamate + phosphate;

CC         Rule:MF_01209};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis;
CC       carbamoyl phosphate from bicarbonate: step 1/1.
CC       {ECO:0000256|HAMAP-Rule:MF_01209}.
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo
CC       pathway; (S)-dihydroorotate from bicarbonate: step 1/3.
CC       {ECO:0000256|HAMAP-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
CC       the large (or ammonia) chain to synthesize carbamoyl phosphate.
CC       {ECO:0000256|HAMAP-Rule:MF_01209}.
CC   -!- SIMILARITY: Belongs to the CarA family. {ECO:0000256|HAMAP-
CC       Rule:MF_01209}.
