Protein attributes

Sequence length	407 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

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 HCO(3)(-): step 1/1. HAMAP MF_01209 Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from HCO(3)(-): step 1/6. 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.
Sequence similarities	Belongs to the carA family. Contains 1 glutamine amidotransferase type-1 domain.
