CD spectrum and conformational distribution of cyclotuftsin in solution
Authors:B.S. Kataev   J.J. Balodis  G.V. Nikiforovich  
Abstract:CD spectra for low-energy conformations of the tuftsin cycloanalogue, , were calculated. A theoretical spectrum obtained as the weighted average of calculated spectra for individual peptide backbone conformers is qualitatively consistent with an experimental CD spectrum in aqueous solution. The conformational distribution allows one to achieve agreement between calculated and experimental values of structural parameters of the cyclotuftsin molecule investigated by NMR spectroscopy.
