Mastoparan X
C73H126N20O15S (1554.9431766000002)
Mastoparan X is a GTP-binding regulatory protein (G protein)-activating peptide, and a tetradecapeptide from wasp venom. Mastoparan X acts function by the direct activation of G protein that couple to phospholipase C to cause secretion from various kinds of cells[1].
mastoparan-V
C73H126N20O15S (1554.9431766000002)
A member of the class of mastopyrans that is a 14-amino acid polypeptide comprising isoleucyl, asparaginyl, tryptophyl, lysyl, glycyl, isoleucyl, alanyl, alanyl, methionyl, alanyl, lysyl, lysyl, leucyl, and leucinamide residues coupled in sequence. It is the major active component of the venom of the hornet Vespa velutina 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 erythrocytes.
