CD spectra of the synthetic δC1b peptide in the presence or absence of metals and comparison with that of a recombinant δC1b domain. The buffer contains 50 mM Tris·HCl (pH 7.5) and 1 mM DTT. Spectra shown are as follows; orange dots, peptide (50 μM) only; blue dots, peptide (50 μM) + 100 μM ZnCl2; yellow dots, peptide (50 μM) + 100 μM ZnCl2 + 100 μM EDTA; light blue dots, the recombinant δC1b domain.
