Magainin 1 (Magainin I) is an antimicrobial and amphipathic peptide isolated from the skin of Xenopus laevis. Magainin 1 exhibits antibiotic activity against numerous Gram-negative and Gram-positive bacteria[1][2][3]. In Vitro: Magainin 1 interacts with acidic lipids through electrostatic interactions followed by hydrophobic interactions to form an amphiphilic helix, inducing the leakage. Magainin 1 induces the leakage of calcein specifically out of negatively-charged vesicles. The peptide binds to bovine brain phosphatidylserine sonicated vesicles according to the Langmuir isotherm with a binding constant of 3.8×105 M-1 and a binding-site number of 0.10 per lipid molecule[2].
