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).

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 ...

The possible regulatory interactions of purified ornithine decarboxylase with DNA-directed RNA polymerases in isolated macronuclei from the ciliated protozoan Tetrahymena thermophila were studied. It has been found that highly purified ODC (specific activity 10.2 mumols CO2 x h-1 x mg-1), even at activities of 37,500 nmol CO2 x h-1 per ml failed to ...
