Abstract
Hydrogen bonds and ion pairs involving side chains play vital roles in protein functions such as molecular recognition and catalysis. Despite the wealth of structural information about hydrogen bonds and ion pairs at functionally crucial sites on proteins, the dynamics of these fundamental chemical interactions are not well understood largely due to the lack of suitable experimental tools in the past. NMR spectroscopy is a powerful tool for investigations of protein dynamics, but the vast majority of NMR methods had been applicable only to the backbone or methyl groups. Recently, a substantial progress has been made in the research on the dynamics of hydrogen bonds and ion pairs involving lysine side-chain NH3(+) groups. Together with computational/theoretical approaches, the new NMR methods provide unique insights into the dynamics of hydrogen bonds and ion pairs involving lysine side chains. Here, the methodology and its applications are reviewed.

On the calculation of 3Jαβ-coupling constants for side chains in proteins
Abstract Structural knowledge about proteins is mainly derived from values of observables, measurable in NMR spectroscopic or X-ray diffraction experiments, i.e. absorbed or scattered intensities, through theoretically derived relationships between structural quantities such as atom positions or torsional angles on the one hand and observable quantities such as squared structure factor amplitudes, NOE intensities or 3 J-coupling constants on the other. The standardly used relation connecting 3 J-couplings...

Conformational analysis by quantitative NOE measurements of the β-proton pairs across individual disulfide bonds in proteins
Abstract NOEs between the β-protons of cysteine residues across disulfide bonds in proteins provide direct information on the connectivities and conformations of these important cross-links, which are otherwise difficult to investigate. With conventional -proteins, however, fast spin diffusion processes mediated by strong dipolar interactions between geminal β-protons prohibit the quantitative measurements and thus the analyses of long-range NOEs across...
