Three novel peptides designated as PNG-1, PNG-K and PNG-R were isolated from the venom of the solitary bee Panurgus calcaratus. They exhibited antimicrobial activity against Grampositive and -negative bacteria and fungi. In this work we focused on the characterization of PNG-R which is unique 25 amino acid residues and two disulfide bridges containing peptide. The secondary structure of PNG-R was studied by circular dichroism spectroscopy measured in water and in the presence of trifluoroethanol or sodium dodecyl sulfate.
