NMR data for conjugate P2-MP. (A) Peptide sequence where residues for which two sets of NMR signals are observed are highlighted in bold. (B) 2D ¹H,¹H-TOCSY spectral region with α-H^N cross-peaks labeled. Some β-H^N cross-peaks are also seen in this region. The inset shows α-ββ′ cross-peaks for F8 and S9 in the two diastereomers. (C) 2D ¹H,¹³C-HSQC spectral region showing ¹Hα-¹³Cα cross-peaks. Experimental conditions: 2 mM peptide in H₂O/D₂O 9:1 v/v, pH 3.1, 45 °C.
