Structural studies of proteins are critical for understanding biological processes at the molecular level. Nuclear magnetic res-onance (NMR) spectroscopy is a powerful technique for obtaining structuralanddynamic informationonproteins and protein-ligand complexes. In the present review, methodologies for NMR struc-ture determination of proteins and macromolecularcomplexes are described. In addition, a number of recent advances that reduce the molecular weight limitations previously imposed on NMR studies of biomolecules are discussed, highlighting applications of these technologies to protein systems studied in our laboratories
