Structure of the backbone in myosin filaments of muscle.
New X-ray data suggest how myosin rods, themselves alpha-helical coiled coils, form the thick filament backbone of crustacean muscles by additional supercoiling. Natural transformations of this structure may describe the myosin backbone in many other animals also.
