Static and kinetic site-specific protein-DNA photocrosslinking: analysis of bacterial transcription initiation complexes.
Static site-specific protein-DNA photocrosslinking permits identification of protein-DNA interactions within multiprotein-DNA complexes. Kinetic site-specific protein-DNA photocrosslinking - involving rapid-quench-flow mixing and pulsed-laser irradiation - permits elucidation of pathways and kinetics of formation of protein-DNA interactions within multiprotein-DNA complexes. We present detailed protocols for application of static and kinetic site-specific protein-DNA photocrosslinking to bacterial transcription initiation complexes.
