Solution structure of RNase P RNA

Representative conformational ensembles that fit SAXS data best. Typical optimized ensembles of indicated size selected for Bst and Eco RNA from the pools of 1051 NMA-perturbed conformations and for Atu RNA from a pool of 13,735 filtered MD-perturbed conformations. For each RNA, minimal ensembles that fit experimental data best are shown on the right, superimposed onto the unperturbed model from Figure 3 (black ribbon).
