[Purification of glutamate dehydrogenase from the rabbit liver and study of its major physico-chemical properties]. 1985

R A Kazarian, and S G Avetisian, and L V Karabashian

Highly purified preparations of glutamate dehydrogenase were obtained from mitochondrial and cytoplasmic fractions of rabbit liver by affinity chromatography on CL-Sepharose 4B modified by adenosine diphosphate. Some physico-chemical properties of the purified enzymes (e. g., specific activity, molecular weight, quaternary structure, stability against denaturating effect of urea, pH optimum of catalyzed reactions, Km values for substrates and coenzymes) were found to be identical. The sole difference was detected in the ability of enzyme preparations to be activated by adenosine diphosphate. The activation of the cytoplasmic enzyme is 160%, that of mitochondrial glutamate dehydrogenase is 230-240% under the same conditions.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008930 Mitochondria, Liver Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix.
