CD spectra of LD4 helix formation. (A) CD spectra showing the molar ellipticity of samples of 20 μM LD4. As the amount of TFE increased, the percent helicity (inset) of the LD4 peptide increased. (B) Change in total helicity of FAT–LD2 samples (50 μM) containing increasing amounts of LD4 (0.2–2 eq). The predictive model that was used is independent of sample concentration.
