Results are reported of a study of the influence of Asp and Glu residues in a peptide chain on the ability of the peptide to co-ordinate to copper(II) ions. The tetrapeptides Asp-Ala-Ala-Ala, Ala-Asp-Ala-Ala, Ala-Ala-Ala-Asp, Asp-Ala-Ala-Asp, Ala-Asp-Asp-Ala, Ala-Asp-Ala-Asp, Ala-Ala-Asp-Asp, Glu-Ala-Ala-Ala, Ala-Glu-Ala-Ala and Ala-Ala-Glu-Ala and the tripeptide Asp-Asp-Asp have been synthesised and their complexes with H+ and Cu2+ ions studied using potentiometry and spectroscopy (visible, CD… CONTINUE READING
