Abstract
X-ray scattering curves for the sperm whale myoglobin molecule and a model which includes only the helical regions of the polypeptide chain are calculated. The portion of the scattering curve associated with the packing of the helices inside the protein globule is analyzed. The model of the myoglobin molecule is used to investigate the sensitivity of the scattering curve to changes in the mutual packing of the helical regions.
