Information on the regulation of urea synthesis in vivo was obtained by examining the relationship between ureagenesis in vivo, citrulline synthesis in vitro, and two factors currently hypothesized to exert short-term regulation of this pathway: the

Previous studies using intact rat liver mitochondria have shown that the soluble matrix enzymes carbamoyl-phosphate synthase (ammonia) (CPS) and ornithine carbamoyltransferase (OCT) display some kinetic properties which would not be observed if they

The pathway of urea synthesis of mammalian liver has proved to be an excellent model for the investigation of the intracellular organization of soluble enzymes. Studies of the behaviour and regulation of the enzymes of this pathway in situ (reviewed

Mitochondrial water spaces were determined by centrifugal filtration, by using 3H2O and [14C]-sucrose, -mannitol, -inulin and -dextran. The volume (in microliter/mg of mitochondrial protein) of each of the spaces was inversely proportional to the amo

It has been proposed that arginine may stimulate urea synthesis in vivo by activating amino acid acetyltransferase and thereby increasing the mitochondrial content of acetylglutamate ( K. Shigesada, K. Aoyagi, and M. Tatibana, 1978 , Eur. J. Biochem.

Experiments with carbamoyl phosphate synthetase (ammonia) in solution and in isolated mitochondria are reported which show the following. NH3 rather than NH4+ is the substrate of the enzyme. The apparent Km of NH3 for the purified enzyme is about 38

Male mice carrying the spfash mutation have 5-10% of the normal activity of ornithine carbamoyltransferase, yet are only slightly hyperammonaemic and develop quite well. A study of liver mitochondria from normal and spfash males showed that they diff

A procedure for the purification of rat liver carbamyl phosphate synthetase (ammonia) to homogeneity is described. The molecular weight of isolated active enzyme is 222,000 ± 10,000; that of the subunits obtained by denaturation with sodium dodecyl

A procedure for the preparation of a very active carbamate kinase is presented. The reproducibility of the purification procedure and some of the kinetic parameters of the enzymatic reaction have been studied. The preparations are essentially homogen
