Abstract
A method of crystallographic analysis to identify myosin heads interac ting with specific actin sites in vertebrate striated muscles is descr ibed. It is based on a Fourier transform of a helix in which probabili ty of occurrence of subunits varies periodically. It predicts the pres ence of layer-lines at 1/24 and 1/10.4 nm(-1) which are experimentally observed in contracting and rigor vertebrate striated muscles, showin g that the myosin heads are interacting with specific sites on actin b ut are still maintaining their average 14.5 nm axial periodicity.
