Amino Acid Sequence
Gly-Ile-Gly-Lys-Phe-Leu-His-Ser-Ala-Gly-Lys-Phe-Gly-Lys-Ala-Phe-Val-Gly-Glu-Ile-Met-Lys-Ser
Application
Initial sites of magainin I binding to E. coli have been shown to be lipopolysaccharide.
Biochem/physiol Actions
Antibiotic peptide. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization, magainins are positively charged and amphiphatic. Binding to artificial neutral membranes has also been demonstrated.
