2D 13C–13C DARR correlation spectra of the TMD in the POPC/cholesterol (left) and POPE (right) membranes. (a, b) Mixed GV and IS-labeled TMD. (c, d) ILSILV-labeled TMD. (e, f) AGILV-labeled TMD. Red and blue assignments denote α-helical and β-strand chemical shifts. The peptide shows a mixture of α-helix and β-strand chemical shifts in the membrane.
