Abstract
Electron microscopy of negatively stained isolated thick filaments of tarantula muscle has revealed that phosphorylation of myosin regulatory light chains is accompanied by a loss of the helical order of myosin heads. From equatorial X-ray diffraction patterns of tarantula muscles in the phosphorylated state we have detected a mass movement in the myosin filaments that supports this finding.
