A Unique Toxic Peptide from the Larvae of the South American Sawfly, Perreyia flavipes
A major toxic component of the South American sawfly larvae, Perreyia flavipes (Pergidae), has been shown to be a heptapeptide with the structure (1). The unique features of this peptide, which has been named pergidin, are the presence of five unnatural D amino acids and a phosphoseryl residue.
