Query: From Conformational Spread to Allosteric and Cooperative models of E.
  coli flagellar motor   Escherichia coli swims using flagella activated by rotary motors. The
direction of rotation of the motors is indirectly regulated by the binding of a
single messenger protein. The conformational spread model has been shown to
accurately describe the equilibrium properties as well as the dynamics of the
flagellar motor. In this paper we study this model from an analytic point of
view. By exploiting the separation of timescales observed in experiments, we
show how to reduce the conformational spread model to a coarse-grained,
cooperative binding model. We show that this simplified model reproduces very
well the dynamics of the motor switch.
