Fig. 5.
Stereoview of the smooth muscle heavy meromyosin model fitted to the three-dimensional reconstruction. Top pair is for standard stereo viewing; bottom pair is for crosseyed stereo viewing. The direction of view is perpendicular to the plane of the crystal (down the z axis of the two-dimensional unit cell). The lipid monolayer would be located below the structure in this view. The "blocked" head is outlined in black. The color scheme for the ribbon diagram is as follows: the heavy chain of the "free" myosin head is magenta and that of the "blocked" head is red. For both myosin heads the converter domain is green, the essential light chains are blue, and the regulatory light chains, orange.
