Coupling of Lever Arm Swing and Biased Brownian Motion in Actomyosin
Figure 7
Contribution of lever-arm swing to the net displacement.
(A) Position near the lever-arm tip and position of the center of mass of the myosin motor domain
are illustrated. (B) Free-energy landscapes drawn in the plane of
in the A.Mpre.ADP.Pi state (left) and in the A.Mclosed state (right). The diagonal line of
is drawn to emphasize that free-energy minima are located at
