    • Dynamics of Bacterial Swarming 

      Darnton, Nicholas C.; Turner, Linda; Rojevsky, Svetlana; Berg, Howard Curtis (Biophysical Society, 2010)
      When vegetative bacteria that can swim are grown in a rich medium on an agar surface, they become multinucleate, elongate, synthesize large numbers of flagella, produce wetting agents, and move across the surface in ...

    • The Gain Paradox 

      Berg, Howard (Elsevier, 2009)
      Chemoreceptors in Escherichia coli control the activity of a kinase that phosphorylates a response regulator that, in turn, biases the direction of rotation of flagellar motors, affecting the manner in which cells swim. A ...

    • Physical Responses of Bacterial Chemoreceptors 

      Vaknin, Ady; Berg, Howard (Elsevier, 2007)
      Chemoreceptors of the bacterium Escherichia coli are thought to form trimers of homodimers that undergo conformational changes upon ligand binding and thereby signal a cytoplasmic kinase. We monitored the physical responses ...

    • 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 ...
