General annotation (Comments)

Catalytic activity	2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate. HAMAP MF_01209
Pathway	Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl phosphate from bicarbonate: step 1/1. HAMAP MF_01209 Pyrimidine metabolism; UMP biosynthesis via de novo pathway; (S)-dihydroorotate from bicarbonate: step 1/3. HAMAP MF_01209
Subunit structure	Composed of two chains; the small (or glutamine) chain promotes the hydrolysis of glutamine to ammonia, which is used by the large (or ammonia) chain to synthesize carbamoyl phosphate By similarity. HAMAP MF_01209
Sequence similarities	Belongs to the carA family. Contains 1 glutamine amidotransferase type-1 domain.
