    • 1 side chain was impossible, information about its orientation was lost. Therefore, the conformation of the Phe side chain could not be calculated and the depicted structures are not representative concerning its orientation.

    • As diastereotopic assignment of the β protons in the side chains of Asp and Arg was impossible, information about the side chain orientation was lost. Therefore, the conformation of the Arg and Asp side chains could not be calculated and the depicted structures are not representative concerning their orientation.

    • note
    • A pyranoid ε-SAA incorporated as a scaffold in a mammalian ribonucleotide reductase inhibitor was shown to be able to adopt a conformation similar to the β-turn conformation of the parent heptapeptide with the SAA replacing the i + 1 and i + 2 residues of the turn.8f It is not excluded that a nine-member intraresidue H bond interaction can also be observed in this ε-SAA-containing peptide.
