Coupling of Lever Arm Swing and Biased Brownian Motion in Actomyosin
Figure 3
The setup for the Langevin molecular dynamics simulations of actomyosin.
An S1 of myosin II (red) with an essential light chain (ELC, blue) and a regulatory light chain (RLC, yellow) is placed on an actin filament (green), which lies along the direction.
s of the actin filament are connected to spatially fixed points by springs, and the lever-arm tip of myosin is constrained to move along a line that runs parallel to the actin filament. The angle around the
-axis is denoted by
.
