• It has been found recently that the bacterial flagellar motor is driven by a proton fluxaccording to its electrochemical potential gradient across the membrane. A model ispresented for the mechanism of rotation of this motor, in which loose coupling isassumed between the proton flux and the motor rotation. A directional torque to rotatethe motor is produced as a result of the interaction in many pairs of two kinds ofmolecules arranged on two rings, which is regulated by the binding of protons. Thetorque is calculated as a function of the electrochemical potential gradient of protonand pH values inside and outside the cell. The results of calculation are compared withexperimental data and some experimental methods for further examination of themodel are proposed.
