Short summary
NMR study of large proteins such as SARS-CoV-2 Main Protease can be challenging when exchange broadening, multiple stable conformations, and back-exchanging the fully deuterated chain pose problems. We demonstrate that 4D NMR, including an extension of 3D NOE-NOE spectroscopy, provides an effective tool for spectral analysis. In combination with X-ray coordinates, the 4D NMR data are particularly useful for extending and validating assignments and for probing structural features.
