==The High-resolution Solution Conformation of an Antimicrobial Peptide Gaegurin 4 and Its Mode of Membrane Interaction==
-
We have applied NMR spectroscopy to determine the high-resolution, structure of gaegurin 4, a 37-residue antimicrobial peptide from Rana, rugosa, under varying hydrophobic conditions. Even in 100% H2O, gaegurin 4, contains a nascent turn near its C-terminal Rana box. Under a more, hydrophobic condition it forms two amphipathic helices, one long, encompassing residues 2-23 and the other consisting of residues 25-34, similar to what has been observed in cecropin A. Functional implication of, the helix-breaking kink at Gly24 in gaegurin 4 was investigated by, preparing several analogs. Based upon the current and previous results, we, propose a novel seaanemone-like ion pore-forming model for gaegurin 4.
