Abstract: The bacterial flagella motor stochastically switches between clockwise (CW) and counterclockwise (CCW) rotation. The switching of flagella motor is regulated by the signalling protein CheY-P with its concentration governed by the bacterial chemotaxis signalling network. Experiments have shown that the switching of bacterial flagella motor is highly cooperative with a Hill coeffiecient around 10. We study the switching regulation of flagella motor by analyical calculation and kinetic Monte Carlo simulation and investigate the dynamic properties of the motor switching.
