Using the model free approach to analyze NMR relaxation data in cases of anisotropic molecular diffusion
Article Abstract:
An anisotropic motional model free approach for analyzing nuclear magnetic resonance relaxation data for molecules undergoing anisotropic rotational diffusion is presented. The approach uses to restriction parameters, (x2 + y2) and (x2 - y2) and can ideally be used for anisotropic overall molecular tumbling. It is also shown that the influence of rotational correlation coefficients for anisotropic diffusion becomes significant for each relaxation parameter.

(super 15)NH backbone dynamics of protein GB1: comparison of order parameters and correlation times derived using various "model-free" approaches
Article Abstract:
A new model-free approach that allows visualization of the distribution of motional correlation times is presented and is used to analyze (super 15)N NMR relaxation data [T1, T2, and {(super 1)H}-(super 15)N NOE], acquired at 500, 600, and 800 MHz, on the uniformly (super 15)N-enriched, 56 residue B1 domain from immunoglubulin protein G (GB1). Nanosecond time scale internal motions are found for all NHs of residues in protein GB1.

Elucidating connectivity and metal-binding structures of unlabeled paramagnetic complexes by [super 13]C and [super 1]H solid-state NMR under fast magic angle spinning
Article Abstract:
A novel approach is described for obtaining connectivities of chemical groups and metal-binding structures for unlabeled paramagnetic complexes by [super 13]C and [super 1]H high-resolution solid-state NMR (SSNMR) by using very fast magic angle spinning. The analysis of [super 1]H anisotropic hyperfine shifts has determined the electron-spin states in Fe(III)-chloroprotoporphyrin-IX in solid states.
