CD spectra of the CB1 C-tail peptide in various detergents. The peptide concentration was 50 μM. (A) CD spectra of the peptide in the absence (■, in black) and presence of 1 mM (▲, in red) or 20 mM (▼;, in blue) DDM. (B) CD spectra of the peptide in the absence (■, in black) and presence 1 mM (▲, in red), 6 mM (▼;, in green), 10 mM (◆, in blue), or 30 mM (●, in red) DOC. (C) CD spectra of the peptide in the absence (■, in black) and presence of 2 mM (▲, in red), 4 mM (▼;, in green), 10 mM (◆, in yellow), 20 mM (●, in blue), 50 mM (□, in red), or 100 mM (△, in light blue) SDS. (D) CD spectra of the peptide in the absence (■, in black) and presence of 0.5 mM (▲, in red), 5 mM (▼;, in green), 50 mM (◆, in blue), or 100 mM (●, in red) DPC. Data represent the average of four experiments. The insets show helicity as a function of detergent concentration. The critical micelle concentration (CMC) of each detergent is indicated (▲, in orange) in the inset.
