The absolute configuration on the chiral nitrogen atom of proline residue in the metal complexes of oligopeptides.
The CD spectra of the Cu(II) and Ni(II) complexes with peptides containing N-terminal L-proline residue are discussed. The formation of the absolute configuration on the bound proline nitrogen is observed in all studied complexes and its contribution to the chiralooptical properties is easily seen in CD spectra.
