Young Investigator Award Lecture. Structures of larger proteins, protein-ligand and protein-DNA complexes by multidimensional heteronuclear NMR.
The recent development of a whole panoply of multidimensional heteronuclear-edited and -filtered NMR experiments has revolutionized the field of protein structure determination by NMR, making it possible to extend the methodology from the 10-kDa limit of conventional 2-dimensional NMR to systems up to potentially 35-40 kDa. The basic strategy for solving 3-dimensional structures of larger proteins and protein-ligand complexes in solution using 3- and 4-dimensional NMR spectroscopy is summarized, and the power of these methods is illustrated using 3 examples: interleukin-1 beta, the complex of calmodulin with a target peptide, and the specific complex of the transcription factor GATA-1 with its cognate DNA target site.
