    • Asymmetry in the Clockwise and Counter-Clockwise Rotation of the Bacterial Flagellar Motor 

      Yuan, Junhua; Fahrner, Karen Alicia; Turner, Linda; Berg, Howard (National Academy of Sciences, 2010)
      Cells of 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 (CCW). Rotation ...

    • Switching dynamics of the bacterial flagellar motor near zero load 

      Wang, Fang; Yuan, Junhua; Berg, Howard Curtis (Proceedings of the National Academy of Sciences, 2014)
      Switching dynamics of flagellar motors of Escherichia coli is commonly observed through markers attached to the flagellar filaments. To eliminate possible complications resulting from the conformational transitions of these ...

    • Ultrasensitivity of an Adaptive Bacterial Motor 

      Yuan, Junhua; Berg, Howard Curtis (Elsevier BV, 2013)
      The flagellar motor of Escherichia coli adapts to changes in the steady-state level of the chemotaxis response regulator, CheY-P, by adjusting the number of FliM molecules to which CheY-P binds. Previous measurements of ...
