Figure 5
(a) Plot of SAXS intensities versus momentum transfer (on the x axis) and the corresponding resolution (on the alternate x axis) comparing experimental (Iobs) with calculated intensities for the possible oligomeric assemblies. The residual R = (Iobs − Iobs)/σIobs represents the discrepancy between the model selected from the crystal structure and the experimental data. (b) Front view and (c) side view of a SAXS envelope calculated from the experimental data with DAMMIF and superimposed with the tetramer ABCD from the crystal structure. |
