One member of a prototypical class of antimicrobial oligomers was used to study pore formation in cardiolipin rich membranes. Using both vesicle dye-leakage assays and small angle x-ray scattering, bilayer remodeling was studied. The results indicate that the presence of negative intrinsic curvature (NIC) lipids is essential for pore formation by this class of molecules: In Gram-positive bacteria, cardiolipin and divalent metal cations like Ca2+ and Mg2+ are needed. This is completely consistent with the role of phosphatidylethanolamine (PE) lipid in Gram-negative bacteria, where antimicrobial activity is dependent on the negative intrinsic curvature of PE, rather than a specific interaction with PE.
