| 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.

| carbamoylphosphate synthetase deficiency | <biochemistry> Carbamoylphosphate synthetase is the initial enzyme of the urea cycle, catalysing the synthesis of carbamoylphosphate from ammonia, bicarbonate and ATP as the first step of ammonia detoxification. The enzyme is an intramitochondrial form called CPS I. A different isozyme found in the cytoplasm, called CPS II, is much less active and apparently not involved in the urea cycle. The deficiency state is autosomal recessive and presents in infancy with massive hyperammonaemia and neurologic deficits in survivors. Diagnosis is suggested by the blood biochemistry and confirmed by specific enzyme assay on liver or rectal biopsy. Prenatal diagnosis by molecular methods has been used successfully in informative families. Inheritance: autosomal recessive. (07 Apr 1998) |
