Speed of the bacterial flagellar motor near zero load depends on the number of stator units

Abstract:

The bacterial flagellar motor (BFM) rotates hundreds of times per second to propel bacteria, driven by an electrochemical ion gradient. The motor consists of a rotor 50 nm in diameter surrounded by up to 11 ion-conducting stator units which exchange between motors and a membrane-bound pool. Measurements of the torque-speed relationship guide the development of models of the motor mechanism. In contrast to previous reports that speed near zero torque is independent of the number of stator unit...
