Protein attributes

Sequence length	450 AA.
Sequence status	Complete.
Protein existence	Inferred from homology.

General annotation (Comments)

Catalytic activity	2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.
Pathway	Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl phosphate from bicarbonate: step 1/1.
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.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the carA family. Contains 1 glutamine amidotransferase type-1 domain.
