Figure 5. Membrane interaction model of the Cdc42-collybistin II complex. (a) The electrostatic potential of the open conformation of the Cdc42-collybistin II complex, calculated at zero ionic strength and contoured at 1.5 kT (blue) and -1.5 kT (red). (b) Model of the interaction between the plasma membrane and the complex in the open conformation. The observed conformation of the Cdc42 C terminus is colored in cyan, whereas the physiologically relevant conformations present in the Cdc42-Dbs and Cdc42-GDI complexes are colored in gray and red, respectively.
