== Publication Abstract from PubMed ==
 +
High-resolution structure elucidation has been challenging for the large group of host-defense peptides that form helices on or within membranes but do not manifest a strong folding propensity in aqueous solution. Here we report the crystal structure of an analogue of the widely studied host-defense peptide magainin 2. Magainin 2 (S8A, G13A, G18A) is a designed variant that displays enhanced antibacterial activity relative to the natural peptide. The crystal structure of magainin 2 (S8A, G13A, G18A), obtained for the racemic form, features a dimerization mode that has previously been proposed to play a role in the antibacterial activity of magainin 2 and related peptides.
