Carbamoyl phosphate synthetase III

Carbamoyl phosphate synthetase III (CPS III) is one of the three isoforms of the carbamoyl phosphate synthetase, an enzyme that catalyzes the active production of carbamoyl phosphate in many organisms.

CPS III (EC 6.3.5.5.) is a ligase (3.) that forms carbon-nitrogen bonds (6.3.) with glutamine as amido-N-donor (6.3.5.) (see BRENDA).
