Protein conformational dynamics play fundamental roles in regulation of enzymatic catalysis, ligand binding, allostery, and signaling, which are important biological processes. Understanding how the balance between structure and dynamics governs biological function is a new frontier in modern structural biology, and has ignited several technical and methodological developments. Among these, CPMG relaxation dispersion solution NMR methods provide unique, atomic‐resolution information on the structure, kinetics, and thermodynamics of protein conformational equilibria occurring on the μs‐ms timescale. Here, we present detailed protocols for acquisition and analysis of 15N relaxation dispersion experiments. As an example, we show the pipeline for the analysis of the μs‐ms dynamics in the C‐terminal domain of bacteria Enzyme I. We provide a detailed description of the protocol implemented in our laboratory for acquisition and analysis of 15N relaxation dispersion profiles by solution NMR spectroscopy.
