Figure 3
Comparison of the 2mF_o − F_c maps and the refined multi-conformer models produced from each serial XFEL experiment. Maps were visualized at multiple contour levels to show evidence of alternative conformations. Following multi-conformer refinement, ensembles were generated from each model using phenix.ensemble_refine. In the right panel, a histogram of the χ₁ angles for residue 113 is plotted for the ensemble. Multi-conformer models plus maps, and the distribution of χ₁ angles across the ensemble models, are similar for all three XFEL data sets.
