Interaction of Cu(II) and Ni(II) with Ypk9 Protein Fragment via NMR Studies
Figure 6
Superimposition of 1H NMR spectra in the aromatic regions for the PK9-H peptide, 2.5 mM, pH 10.5, and 298 K, with increasing amounts of Ni(II) from 1 : 0.25 to 1 : 0.90 metal to ligand molar ratios. New resonances due to Ni-binding have been labelled by asterisk*.
