A right handed peptide helix containing a central double D-amino acid segment.
The crystal structure of the 13 residue peptide Boc-Leu-Aib-Val-Ala-Leu-Aib-Val-DAla-DLeu-Aib-Leu-Aib-Val-OMe reveals a continuous helical conformation providing an unambiguous characterization of contiguous D-residues in a right handed peptide helix.
