Far-UV CD spectra of the AS1- and AS2-containing peptides in the presence of LUVs. The peptides analyzed are constituents of the HAMP domains from (A) Af1503, (B) EnvZEc, (C) NarXEc, and (D) TarEc. Samples contained a final concentration of 50 μM peptide (AS1p-, AS2p- or a 1:1 mix) in 50 mM sodium phosphate buffer (pH 7.2) (left panel), buffer with an additional 1 mM POPC (center panel), or buffer with an additional 1 mM POPC/POPG 4:1 (right panel).
