1. Rabbit antiserum was raised against purified carbamoyl-phosphate synthase (ammonia) from rat liver. 2. The antiserum proved to be specific in double-diffusion test and reacted in an in situ immunohistochemical test on rat liver proteins fractionated on a sodium dodecyl sulphate polyacrylamide gel only in the region where carbamoyl-phosphate synthase

The possibility of control of the activity of carbamoyl-phosphate synthase (ammonia) (EC 2.7.2.5) in rat-liver mitochondria by variation in the intramitochondrial free Mg2+ concentration has been investigated. Carbamoyl-phosphate synthase activity was measured by coupling the formation of carbamoylphosphate to the synthesis of citrulline in a reaction ...

Abstract 1. 1. In fractionations of liver of Ambystoma mexicanum carbamoyl-phosphate synthase (ammonia) activity was only strikingly enriched in the mitochondrial fraction. 2. 2. If the mitochondrial fraction had a low respiratory control ratio sometimes some of the activity could be demonstrated in the soluble fraction which was thought to

Journal of Experimental Zoology, 1982
AbstractA method has been developed to establish the degree of cross‐reactivity of an antiserum raised against purified carbamoyl‐phosphate synthase (ammonia) from adult rat liver, toward a homologous enzyme from another species without purification of the latter enzyme.

1. In axolotl liver, the activity of carbamoyl-phosphate synthase (ammonia), expressed per mg liver protein, decreases to a minimum at 5 months of age, then increases to a maximum at 8 months of age which is followed by a decrease again. The initial decrease between 3 and 5 months of age appears to be largely due to an increase in non-carbamoyl ...

Mechanisms of Ageing and Development, 1983
To analyze the changes in rat-liver carbamoyl-phosphate synthase (Cpase) protein levels during ontogenesis, these levels were determined by means of two independent methods, i.e. radioimmunoassay and densitometric assay. During normal development the changes in catalytic activity of Cpase are accompanied by equivalent changes in the quantities of ...

Regulation of carbamoyl-phosphate synthase (ammonia) in liver in relation to urea cycle activity
Trends in Biochemical Sciences, 1979Abstract The properties of carbamoyl phosphate synthase (ammonia) are extremely interesting from the point of view of metabolic regulation and make the enzyme the main candidate for the rate-controlling step in urea synthesis.
