Chemical Relaxation Kinetic Studies of E. coli RNA Polymerase Binding to Poly [d(AT)] Using Ethidium Bromide as a Fluorescence Probe

Part of the Molecular Biology Biochemistry and Biophysics book series (MOLECULAR, volume 24)


Many and perhaps most of the biosynthetic and control mechanisms of a cell are mediated through protein-nucleic acid interactions. Such phenomena are necessarily complex in nature since they involve multisite associations between macromolecules and are subject to a multitude of thermodynamic and environmental influences (temperature, pH, ionic strength, ligands etc.). Unfortunately, detailed information about these processes is available for very few systems to date, due in part to the use of indirect experimental methods (activity measurements, filter binding, ultracen- trifugal analysis, etc.). Kinetic data, in particular, often have been obtained under extreme conditions which may not typify the physiological state.
