Abstract
An empirical equation, describing the relationship between the porphyrin methyl hyperfine shifts and the position of the axial ligand(s), has been applied to an artificial heme-protein in order to obtain insight into the active site properties of heme-protein models.

Standard procedures for using nuclear Overhauser enhancements (NOE) between protons to generate structures for diamagnetic proteins in solution from NMR data may be supplemented by using dipolar shifts if the protein is paramagnetic. This is advantageous since the electron -nuclear dipolar...

De novo determination of internuclear vector orientations from residual dipolar couplings measured in three independent alignment media
De novo determination of internuclear vector orientations from residual dipolar couplings measured in three independent alignment media
Ke Ruan, Kathryn B. Briggman and Joel R. Tolman
Journal of Biomolecular NMR; 2008; 41(2) pp 61 - 76
Abstract:
The straightforward interpretation of solution state residual dipolar couplings (RDCs) in terms of internuclear vector orientations generally requires prior knowledge of the alignment tensor, which in turn is normally estimated using a structural model. We have developed a protocol which allows the requirement for prior structural knowledge to...

J. Am. Chem. Soc.; 2006; 128(39) pp 12910 - 12916; (Article)
Abstract:
Rational drug design depends on the knowledge of the three-dimensional (3D) structure of complexes between proteins and lead compounds of low molecular weight. A novel nuclear magnetic resonance (NMR) spectroscopy strategy based on the paramagnetic effects from lanthanide ions allows the rapid determination of the 3D structure of a small...
