  1. The 15N-amino acid position in the peptide is reported. Theoretical chemical shift values were derived from http://www.bmrb.wisc.edu/ref_info/statful.htm and corrected [29]. Experimental chemical shift values were derived from resonance spectra reported in Fig. 4. The average value of chemical shifts relative to the H and N atoms of α amino residue, and the H and N atoms of η amino residues are reported for Arg-11 (data from: http://www.bmrb.wisc.edu/ref_info/statful.htm). The chemical shifts relative to the H and N atoms of α amino residue in Arg-1 are undetectable because of terminal position of the amino acid in the peptide. n.d., not detected.
