title = "Nuclear magnetic resonance relaxation in determination of residue-specific 15N chemical shift tensors in proteins in solution: Protein dynamics, structure, and applications of transverse relaxation optimized spectroscopy",
abstract = "We developed several approaches to direct determination of the 15N CSA from relaxation measurements in uniformly 15N-labeled proteins in solution. These methods are based on multiple-field measurements and could be extended to other nuclei in proteins and other molecules. Combined with the isotropic chemical shift measurements, this provides an experimental approach to full characterization of chemical shift tensors in proteins in their native milieu, which is likely to provide valuable information on the nature of chemical shifts and their relation to protein structure. Knowledge of 15N CSA is essential for an accurate characterization of protein dynamics from relaxation measurements.",
