Multidimensional NMR methods for protein structure determination

Abstract

Structural studies of proteins are critical for understanding biological processes at the molecular level. Nuclear magnetic resonance (NMR) spectroscopy is a powerful technique for obtaining structural and dynamic information on proteins and protein-ligand complexes. In the present review, methodologies for NMR structure determination of proteins and macromolecular complexes 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.
