Abstact

Essential understanding: Elucidation of structural requirements and interactions of antimicrobial peptides with lipopolysaccharide (LPS) are essential to understand the mechanism of action of antimicrobial peptides. The highly active antimicrobial peptide MSI-594 (see figure for electrostatic potential surface) acquires a novel helical hairpin structure in complex with LPS. The structure and interactions of MSI-594 with LPS presented here provide important insights into the mechanism of outer membrane permeabilization by antimicrobial peptides.
