<p>Cross section pair distribution functions of rabbit F-actin (dashed line), polymerized ActM (dotted) and polymerized ActM with PfnM in molar ratios of 2∶1, 1∶1 and 1∶2 (solid, dash-dotted, shot dotted line, respectively). Maximum dimensions at <i>p</i><sub>c</sub>(<i>r</i>) = 0 are at 9 nm, 20 nm, 25 nm and 35 nm. Inset: Magnification of the region around the maxima of the <i>p</i><sub>c</sub>(<i>r</i>).</p
