Notes: Alamethicin is an antibiotic peptide belonging to a class of membrane active peptides of fungal origin called peptaibols.{20878} It contains an unusual amphiphilic amino acid, 2-aminoisobutyric acid, which strongly induces helical peptide structures and forms voltage-gated ion channels in the lipid bilayers of cell membranes.{20878} Alamethicin is often used to study ion channel assembly, voltage gating, and peptide-membrane interactions.{20877,20879,20876,20875} Alamethicin is also widely used as agent to induce various physiological and defense responses in eukaryotic cells including plants.{20878}
