| butyryl-CoA synthetase | Fatty acid thiokinase (medium chain), a ligase forming acyl-CoA's from medium-chain fatty acids and CoA with the conversion of ATP to AMP and PPi. A key step in activation of fatty acids. Synonym: acyl-activating enzyme, butyryl-CoA synthetase, octanoyl-CoA synthetase. (05 Mar 2000) |
| canavaninosuccinate synthetase | <enzyme> Aspartate + ureido homoserine + ATP yields canavaninosuccinate + AMP + ppi Registry number: EC 6.3.4.- (26 Jun 1999) |
| 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.
