Fig. 4.
One-dimensional solid-state NMR spectra of CHIF in (A,C) oriented and (B,D) unoriented lipid bilayers at 22 °C. (A,B) 31P chemical shift spectra from the phosphate headgroups of the phospholipids. (C,D) 15N chemical shift spectra of uniformly 15N-labeled CHIF. The 15N and 31P shifts are referenced to 0 ppm for external liquid ammonia and phosphoric acid.
