Sequential Isolation of Superoxide Dismutase and Ajmaline from Tissue Cultures of Rauwolfia serpentinaBenth
TLDR
Two biologically active compounds, the enzyme superoxide dismutase (EC 1.15.1) and the anti-arhythmic indole alkaloid ajmaline, were isolated from a callus culture of Rauwolfia serpentinaBenth to obtain highly purified products.
Molecular-genetic and biochemical characteristics of citrate synthase from the citric-acid producing fungus Aspergillus niger
TLDR
The fundamental molecular-genetic and biochemical characteristics of the enzyme from this producer are discussed in comparison with those of other eukaryotes and can be helpful in the development of a strategy for the design of more effective producers of organic acids.
Effect of Phytohormones on the Protein-Synthesizing Ability of Rauwolfia serpentinaBenth. Tissue Culture
TLDR
Changes in the concentration of total protein in cells induced by indolylacetic and naphthylacetic acids were shown to be associated with the effects of these phytohormones on the biosynthesis and degradation of intracellular protein.
[Effect of ionizing radiation on the turnover of catalase-degrading proteinase in rat hepatocytes].
TLDR
The authors discuss the possibility of a correlation between the decrease in the catalase protein degradation and the level of proteinase activity in hepatocytes of irradiated rat liver.
[Insulin degradation in hepatocytes and erythrocytes of rats in normal condition and in experimental diabetes].
TLDR
Results suggest that insulin-degrading activity in erythrocytes and hepatocytes is regulated by endogenous inhibitors, by synthesis of insulinase, and this change of blood insulin concentration influences practically all the components of insulin- degrading complex.
Metabolic characteristics of citric acid synthesis by the fungus Aspergillus niger
TLDR
The paper reviews the influence of some fermentation conditions (medium components, additives, and technological parameters) on metabolic processes in producing cells, which is important for an integral understanding of both biosynthesis process at the cellular level and fermentation technology.
