Attenuated total reflection (ATR) Fourier transform infrared spectroscopy (FTIR) was used to investigate the secondary structure of two pore-forming cytolysins from the sea anemone Stichodactyla helianthus and their interaction with lipid membranes. Frequency component analysis of the amide I' band indicated that these peptides are composed predominantly of beta structure, comprising 44-50% beta-sheet, 18-20% beta-turn, 12-15% alpha-helix, and 19-22% random coil. Upon interaction with lipid… CONTINUE READING
