| 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) |

| carbamoyl-phosphate synthase (ammonia) |
[EC 6.3.4.16] an enzyme of the ligase class that catalyzes the synthesis of carbamoyl phosphate from ammonia and carbon dioxide, the first committed step in the urea cycle (see illustration at urea cycle, under cycle). The reaction occurs predominantly in liver mitochondria, requires N-acetylglutamate as a cofactor, and hydrolyzes two molecules of ATP. Decreased enzyme activity, an autosomal recessive trait, causes carbamoyl phosphate synthetase deficiency.
