Syringomycin-E (SR-E) is a cyclic lipodepsinonapeptide produced by certain strains of the bacterium Pseudomonas syringae pv. syringae. It shows inhibitory effects against many fungal species, including human pathogens. Its primary biological target is the plasma membrane, where it forms channels comprised of at least six SR-E molecules. The high-resolution structure of SR-E and the structure of the channels are currently not known. In this paper, we investigate in atomic detail the molecular features of SR-E in water by NMR and in water and octane by molecular dynamics simulation (MD). We built a model of the peptide and examined its structure in water and octane in 200 ns MD simulations both with and without distance restraints derived from NMR NOE data. The resulting trajectories show good agreement with the measured NOEs and circular dichroism data from the literature and provide atomistic models of SR-E that are an important step toward a better understanding of the antifungal and antibacterial activity of this peptide.
