General annotation (Comments)

Function

Involved in the urea cycle of ureotelic animals where the enzyme plays an important role in removing excess ammonia from the cell By similarity.

Catalytic activity

2 ATP + NH3 + CO2 + H2O = 2 ADP + phosphate + carbamoyl phosphate.

Enzyme regulation

Requires N-acetyl-L-glutamate (NAG) as an allosteric activator By similarity.

Subcellular location

Mitochondrion.

Sequence similarities

Contains 2 ATP-grasp domains.

Contains 1 glutamine amidotransferase type-1 domain.
