Structure of the backbone in myosin filaments of muscle

Nature. 1979 Jan 4;277(5691):37-40. doi: 10.1038/277037a0.


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.
