| carbamoyl-phosphate synthase (glutamine-hydrolyzing) | <enzyme> An enzyme that catalyses the formation of carbamoyl phosphate from ATP, carbon dioxide, and glutamine. This enzyme is important in the de novo biosynthesis of pyrimidines. Chemical name: Carbon dioxide:L-glutamine amido-ligase (ADP-forming, carbamate-phosphorylating) Registry number: EC 6.3.5.5 (12 Dec 1998) |
| carbamoyl phosphate synthetase | A phosphotransferase catalyzing the formation of carbamoyl phosphate. There are two significant isozymes. Carbomoyl phosphate synthetase I is a mitochondrial enzyme that catalyses the reaction of 2ATP, NH3, CO2, and H2O to carbamoyl phosphate, 2ADP, and Pi. It is activated by N-acetylglutamate and participates in urea biosynthesis. A deficiency of carbamoyl phosphate synthetase I can result in hyperammonaemia. Carbamoyl phosphate synthetase II is a cytosolic enzyme that, under physiological conditions, uses l-glutamine as the nitrogen source (producing l-glutamate) instead of NH3, is not activated by N-acetylglutamate, and is found in pyrimidine biosynthesis.
