Abstract

Mast cell degranulating peptide, a toxin of bee venom, is a polypeptide composed of 22 amino acids. Exposure of the asolectin bilayer to the peptide results in the formation of channels that are more permeable to K+ than Cl-. These channels are activated when the voltage of the cis side, to which the peptide is added, is made positive.
