The aryl hydrocarbon receptor (AhR) mediates a variety of biological responses to ubiquitous environmental pollutants. AhR is ligand activated transcription factor with high affinities for aromatic planar compounds such as β-naphthoflavone (BNF), 3-methylcholanthrene (3-MC), benzo[a]pyrene (BaP) or dioxin (TCDD).

Mitochondrial DNA-directed RNA polymerase from Saccharomyces cerevisae mitochondria
Biochemical and Biophysical Research Communications, 1971Abstract A DNA-directed RNA polymerase activity has been detected in yeast mitochondrial extracts which is sensitive to rifampicin. This activity is distinct from that found in the nucleus and cytoplasm, and is possibly coded for, or under the control of the mitochondrial genome.

Polyacetylenetriol (PAT), a natural marine product from the Mediterranean sea sponge Petrosia sp., was found to be a novel general potent inhibitor of DNA polymerases. It inhibits equally well the RNA- and DNA-dependent DNA polymerase activities of retroviral reverse transcriptases (RTs) (i.e.

Enzymatic machineries fundamental for information processing (e.g., transcription, replication, translation) in Archaea are simplified versions of their eukaryotic counterparts. This is clearly noticeable in the conservation of sequence and structure of corresponding enzymes (see for example the archaeal DNA-directed RNA polymerase (RNAP)). In Eukarya,

Biological Chemistry Hoppe-Seyler, 1989
Stimulation of growth in resting cultures of the ciliated protozoan Tetrahymena thermophila stimulated putrescine formation in a manner coordinated to transcription and partly to DNA-polymerisation. The stimulation of polyamine biosynthesis involved increased formation of the precursor L-ornithine from L-arginine as well as stimulation of the ...

DNA-directed RNA polymerase was solubilized from total HeLa cells. Three distinct classes of the enzyme could be clearly differentiated by their sensitivity toward alpha-amanitin. While form A is completely resistant to high concentrations (133 mug/ml) of this toxin, enzyme B is highly sensitive and is completely inhibited by concentrations of 0.1 mug ...
