General annotation (Comments)

Catalytic activity

2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate. HAMAP MF_01210

Cofactor

Binds 4 manganese ions per subunit. HAMAP MF_01210

Pathway

Amino-acid biosynthesis; L-arginine biosynthesis; carbamoyl phosphate from HCO(3)(-): step 1/1. HAMAP MF_01210

Pyrimidine metabolism; UMP biosynthesis via de novo pathway; UMP from HCO(3)(-): step 1/6. HAMAP MF_01210

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. Tetramer of heterodimers (alpha,beta)4. HAMAP MF_01210

Sequence similarities

Belongs to the carB family.

Contains 2 ATP-grasp domains.
