The argument and experimental evidence are presented for a two-state model that explains the action of both helical and β-sheet antimicrobial peptides after they bind to the plasma membranes of cells. Each peptide has two distinct physical states of binding to lipid bilayers. At low peptide-to-lipid ratios (P/L), the peptide tends to adsorb in the lipid headgroup region in a functionally

2 Jul 2015 We investigate the mechanisms of AMPs in action at different levels of detail: from atomistic [1, 2] to coarse grained molecular dynamics (MD)

Antimicrobial peptides (AMPs) are a promising alternative to classical antibiotics in the fight against multi-resistant bacteria. They are produced by organisms from all domains of life and constitute a nearly universal defense mechanism against infectious agents. No drug can be approved without information about its mechanism of action. Peptides undergo changes in conformation and aggregation state in the presence of membranes; conversely, lipid conformation and packing can adapt to the presence of peptides. As a consequence, a single peptide can act through several mechanisms depending on the peptide's structure, the peptide:lipid ratio, and the properties of the lipid membrane.
