  • Title: [Effect of alpha-tocopherol and ubiquinone on mitochondrial RNA polymerase activity. The role of tocopherol-binding proteins].
    Author: Petrova GV, Kapralov AA, Izhokina IA, Donchenko GV.
    Journal: Biokhimiia; 1994 Apr; 59(4):575-81. PubMed ID: 8018780.
    Abstract:
    It has been shown that alpha-tocopherol within the complex with tocopherol-binding proteins, in contrast with free tocopherol, decreases the RNA-polymerase activity in isolated rat liver mitochondria. Both free and complexed to proteins alpha-tocopherol increases the RNA-polymerase activity in isolated nuclei. The effect of alpha-tocopherol is conditioned mostly by the nature of the tocopherol-binding proteins. It has been established that ubiquinone complexed to tocopherol-binding proteins from mitochondria can also change the level of RNA synthesis. The effect of alpha-tocopherol and ubiquinone are not additive.
