Following the Behavior of the Flagellar Rotary Motor Near Zero Load.

J Yuan1, H C Berg.   

Abstract

At room temperature at stall, the flagellar motor of the bacterium Escherichia coli exerts a torque of ~1300 pN nm. At zero external load, it spins ~330 Hz. A robust method for studying the motor near zero load is reviewed here.
