The correlation between protein binding to DNA and DNA bending has been observed in many protein-DNA complex structures. These are, however, the correlation in static structures. Due to time and spatial resolutions in experiments, little is known on the dynamic coupling between protein binding and DNA bending. Here, armed with new simulation methods, we investigated the dynamic coupling between protein binding and DNA bending for a bacterial protein HU and 14 other proteins. The sliding of positively-charged HU on negatively-charged DNA is highly coupled with local DNA distortion, which is reminiscent of polaron in physics. In shorter time scale, HU was self-trapped in a locally bent DNA leading to pauses. Spontaneous relaxation in DNA shape resulted in the sliding mode.
