Schematic diagram of the layer-line reflections observed in the small-angle X-ray diffraction pattern from the resting ABRM. The abscissa R shows the radial (i.e. parallel to the equator) distance from the meridian in the reciprocal space. The long broken lines represent thin-filament reflections. The layer-line number l and the order of the Bessel function n shown on the right-hand scale are assigned on the basis of a 28/13 left-handed genetic helix of actin with a structural period of 775.4 Å (Tajima et al., 1994BB18). The short straight lines on and near the meridian represent the thick-filament reflections. The layer-line number k and the order of the Bessel function h shown on the left-hand scale are assigned after Bear & Selby (1956BB4) with a structural period of 726.63 Å (Tajima et al., 1994BB18).
