Characterization of BmKbpp, a multifunctional peptide from the Chinese scorpion Mesobuthus martensii Karsch: Gaining insight into a new mechanism for the functional diversification of scorpion venom peptides

► BmKbpp possesses strong antimicrobial activity against the majority of tested bacteria and fungi with very weak hemolytic activity. ► BmKbpp markedly inhibits the superoxide production in granulocytes at low concentration. ► Both BmKbpp and the C-terminal region of BmKbpp possess bradykinin-potentiating activity. ► Multi-functionalization of a single peptide could be a new mechanism for the functional diversification of scorpion venom peptides.
