Ensemble modelling results for CaM. (a) I(q) versus q (black squares) with the EOM model (red line) and error-weighted difference plot for the model and experimental profiles (red squares). (b) Averaged and filtered DAMMIN model (grey spheres) overlaid with representative structures from the optimized ensemble. Structures are aligned by their N-terminal domains (magenta), showing variability in the relative disposition of the C-terminal domains (cyan). The calcium ions are depicted as yellow spheres. Given the variations in the selected structures, the overlay with the DAMMIN model was performed simply by eye in PyMOL. (c, d) Rg and dmax distributions, respectively, from EOM for the starting pool (black line) and the optimized ensemble (red line). |
