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

      Yuan, Junying; Berg, Howard (Springer Verlag, 2009)
      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. Techniques for studying the motor near zero load are novel and ...
    • Switching of the Bacterial Flagellar Motor Near Zero Load 

      Yuan, Junhua; Fahrner, Karen Alicia; Berg, Howard (Elsevier, 2009)
      Flagellated bacteria, such as Escherichia coli, are able to swim up gradients of chemical attractants by modulating the direction of rotation of their flagellar motors, which spin alternately clockwise (CW) and counterclockwise ...
