  • A strategy is presented for complete identification of 1H spin systems of lysine residues using sophisticated 2D NMR experiments. Relayed and remote connectivities within each spin system are determined for spin subsystems based at the backbone amide and C epsilon proton resonances. When complete spin system identification is combined with sequence-specific assignment, protein surface structure and dynamics can be probed in a site-specific manner. The interaction between the five lysine residues of French bean plastocyanin and a model redox partner Cr(CN)6(3-) has been examined using this approach.
