The binary complexes of transition metal ions with dipeptides or nucleobases have already been well-characterized and the most important findings were rewieved by several authors [1, 2]. In case of oligopeptides the metal binding ability of the ligands depends on the the involvement of amide nitrogens and side chain residues in metal ion coordination. Copper(II) and palladium(II) were reported to be the most effective to induce deprotonation and coordination of amide nitrogens and, as a consequence, these metal ions form especially stable complexes with dipeptides.
