Melittin is a small protein that is the principal cytotoxic component of venom of the honey bee, A. mellifera.¹ Structurally, melittin consists of two α-helical segments forming a bent rod, with hydrophilic residues on the convex side and hydrophobic sites on the concave side.^1,2 This allows melittin molecules to assemble as tetramers on membrane surfaces and form pores, resulting in cell death. Bee venom is also known to stimulate phospholipase A₂ (PLA₂) activity, and this may be linked to melittin-mediated pore production as well as the presence of low molecular weight PLA₂ enzymes in the venom.^2,3 Melittin also has antimicrobial properties, which, combined with its cytolytic properties, extends its potential for therapeutic applications.³
