摘要:
The complete main chain and approximately 75% of the side chain H-1-NMR assignments of the 129-residue protein, turkey egg-white lysozyme, are presented. NOE data, hydrogen-exchange rates, chemical shifts and coupling constants are reported and are indicative of a structure in solution that is essentially identical to that of the homologous hen egg-white lysozyme. The NH-alphaCH coupling constants of turkey lysozyme are compared to torsion-angle data from three crystal structures of the protein and the results are interpreted in terms of crystal-structure resolution and refinement.
