Due to their dynamic nature relevant to biological activity, biomolecules frequently interconvert between functional substates. Determining how these visits to different conformational states are physically characterized remains a challenging task. We employ computational strategies in conjunction with NMR experiments to reveal – in atomistic resolution – features of transition states and molecular mechanisms along conformational pathways of the signaling protein Nitrogen Regulatory Protein C (NtrC) and the enzyme Adenylate Kinase (Adk).
