A metallopeptide comprises a peptide bonded to a metal cation at two coordinating amino acid residues that are aqueous solvent-accessible, the metallopeptide having a secondary structure which is stabilized by the bonded metal cation. The secondary structure is a beta sheet having a beta turn, and the coordinating amino acid residues are located at relative amino acid positions of i and i+3 or i-1 and i+5 on the polypeptide.
