CC   -!- CATALYTIC ACTIVITY: 2 ATP + L-glutamine + HCO(3)(-) + H(2)O = 2
CC       ADP + phosphate + L-glutamate + carbamoyl phosphate.
CC   -!- PATHWAY: Amino-acid biosynthesis; L-arginine biosynthesis;
CC       carbamoyl phosphate from bicarbonate: step 1/1.
CC   -!- PATHWAY: Pyrimidine metabolism; UMP biosynthesis via de novo
CC       pathway; (S)-dihydroorotate from bicarbonate: step 1/3.
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       Tetramer of heterodimers (alpha,beta)4.
CC   -!- SIMILARITY: Belongs to the CarA family. {ECO:0000305}.
