Internal Normal Mode Analysis applied to RNA flexibility and conformational changes

Abstract: We investigated the capability of internal normal modes to reproduce RNA dynamics and predict observed RNA conformational changes, and, notably, those induced by the formation of RNA-protein and RNA-ligand complexes. Here, we extended our iNMA approach developed for proteins to study RNA molecules using a simplified representation of RNA structure and its potential energy. Three datasets were also created to investigate different aspects. Despite all the approximations, our study shows that iNMA is a suitable … Show more

“…There are several methods to sample the conformational ensemble from a starting RNA structure, including Molecular Dynamics simulations (18), Monte Carlo-based methods, such as SimRNA (20), Normal Modes (14, 21, 22), and robotics-inspired motion planning approach (KGSRNA (23)). However, there is only one predictor of metal ion positions in RNA, MetalionRNA (24), based on a statistical analysis of ions in the PDB.…”
