EMD-3301 is the volume derived from 3D image reconstruction of the best ordered filaments from the same image data from which the worst ordered filament volume of this deposition was obtained. The best ordered structure is described in Z. Hu, D. W. Taylor, M. K. Reedy, R. J. Edwards, K. A. Taylor, Structure of myosin filaments from relaxed Lethocerus flight muscle by cryo-EM at 6 Angstrom resolution. Sci. Adv. 2, e1600058 (2016).
