Abstract: The spatial structure of a synthetic fragment of SEVI – heptapeptide Glu-Ile-Leu-Asn-His-Met-Lys – in solution and in the complex with a model cell membrane surface (a micelle based on sodium dodecyl sulfate) was determined and described by $^1\mathrm H$ NMR spectroscopy and two-dimensional NMR (TOCSY, HSQC-HECADE, NOESY) spectroscopy. The complexation was confirmed by the change in the chemical shifts of the heptapeptide's $^1\mathrm H$ NMR spectra as well as by the signs and values of NOE effects in various media. A comparison of the spatial structure of heptapeptide Glu-Ile-Leu-Asn-His-Met-Lys in water solution and in the complex was made.
Keywords: oligopeptides, micelles, NMR $^1\mathrm H$ spectroscopy, TOCSY, NOESY.
