Interaction of Cu(II) and Ni(II) with Ypk9 Protein Fragment via NMR Studies

Figure 8

Selection of aliphatic regions in the ¹³C-¹H HSQC NMR spectra for PK9-H peptide, 2.5 mM, pH 10.5, and 𝑇 298 K, in the absence (blue) and in the presence (red) of 0.9 equivalents of Ni(II). New resonances due to Ni-binding have been labelled.
