Coupling of Lever Arm Swing and Biased Brownian Motion in Actomyosin

Figure 4

Free-energy landscapes of actin-myosin interactions.

Two-dimensional free-energy landscapes are drawn in the plane of the coordinate of the center of mass of the myosin head as contour maps in units of (right), and one-dimensional free-energy landscapes on the coordinate (left). Landscapes in A. M^pre.ADP.P_i (top), A.M^post.ADP (middle), and A.M^closed (bottom).
