SFG signals from GRK52–31 indicate strong association with model membranes and helical character in a more hydrophobic environment. (a) Spectra in the C–H and O–H stretching frequency region detected from the interface between the POPC/POPC bilayer and buffer alone (black), GRK52–31 in 10 mM phosphate buffer pH 7.4 (red), after washing (blue), and in a mixture of 60% buffer/40% TFE (dark cyan). (b) SFG spectra of GRK52–31 associated with a POPC/POPC bilayer in contact with peptide solution in 60% 10 mM phosphate buffer pH 7.4/40% TFE in the amide I frequency region. (c) SFG spectra of GRK52–31 associated with a POPC/POPC bilayer in contact with 60% PBS/40% TFE.
