Isolated from the venom of the Taiwan
hornet Vespa basalis. | [Definition]
ChEBI: A member of the class of mastopyrans that is a 14-amino acid polypeptide comprising leucyl, lysyl, leucyl, lysyl, seryl, isoleucyl, valyl, seryl, tryptophyl, alanyl, lysyl, lysyl, valyl, and leucinamide residues coupled in sequence. It is the major active
omponent of the venom of the hornet Vespa basalis and causes degranulation of mast cells. It exhibits antimicrobial activity against both Gram-positive and -negative bacteria as well as haemolytic activity on chicken, human and sheep erythrocy
es. | [Hazard]
A poison. | [Uses]
Mastoparan B is an antimicrobial peptide derived from hornet Vespa. Mastoparan B can cause the shape of red blood cells to change from normal disk-like to serrated[1]. | [References]
