syringomycin (cas 11140-67-3) E (SRE) is a member of a family of lipodepsipeptides that characterize the secondary metabolism of the plant-associated bacteria Pseudomonas syringae pv. syringae. It displays phytotoxic, antifungal and haemolytic activities, due to the membrane interaction and ion channel formation. To gain an insight into the conformation of SRE in the membrane environment, we studied the conformation of SRE bound to SDS micelle, a suitable model for the membrane-bound SRE. In fact, highly similar circular dichroism (CD) spectra were obtained for SRE bound to sodium dodecylsulphate (SDS) and to a phospholipid bilayer, indicating the conformational equivalence of SRE in these two media, at difference with the CD spectrum of SRE in water solution. The structure of SDS-bound SRE was determined by NMR spectroscopy combined with molecular dynamics calculations in octane environment. The results of this study highlight the influence of the interaction with lipids in determining the three-dimensional structure of SRE and provide the basis for further investigations on structural determinants of syringomycin E-membrane interaction.
► SDS micelle and phospholipids induce modifications in the three-dimensional structure of syringomycin E. ► Conformation of syringomycin E in SDS micelle was studied by NMR spectroscopy and molecular dynamics calculations.
