Definition:A member of the class of mastopyrans that is a 14-amino acid polypeptide comprising isoleucyl, asparaginyl, leucyl, lysyl, alanyl, leucyl, alanyl, alanyl, leucyl, alanyl, lysyl, lysyl, isoleucyl, and leucinamide residues coupled in sequence. It is the major active component of the venom of the vespid wasp, Vespula lewisii and causes degranulation of mast cells.
