Abstract

A review is given of the structure and dynamics of the flagellar rotary motor. Force-generating elements in a motor driving a tethered bacterium (a cell fixed to the substratum by a single flagellum) exert forces of order 20 pN while moving at speeds of order 1 micron/s. Force-generating elements in a motor driving a flagellar filament in a bundle exert forces some 10-fold lower but move at speeds more than 10-fold higher. The motor torque-speed relationship has been measured over a wide dynamic range. Motors strongly resist being driven backwards and are easily broken.

摘要

本文综述了鞭毛旋转马达的结构和动力学。驱动拴系细菌（通过单根鞭毛固定在基质上的细胞）的马达中的力产生元件在以约1微米/秒的速度移动时施加约20皮牛的力。驱动成束鞭毛丝的马达中的力产生元件施加的力约低10倍，但移动速度高出10倍以上。已在很宽的动态范围内测量了马达的扭矩-速度关系。马达强烈抵抗向后驱动且容易损坏。
