Figure S2. Layer lines plot. Averaged layer line dataset used to calculate a 3D map of a 15-protofilament microtubule with a KLP10A MD construct spiral. The indexes N and L are, respectively, the Bessel order and layer line number. The horizontal scale is in Å^-1. Solid lines are the amplitudes, and dotted lines the phases (-180° to 180°). The vertical amplitude scale (arbitrary units) is scaled for each layer line plot.
