(a) Schematic of the magnetically aligned lipid bilayer (blue) and inserted Pf3_24_2 (gray). θ is the angle formed between the helix long axis of Pf3_24_2 and the membrane normal. (b) 1H-15N SAMPI4 spectra of Pf3_24_2 (Fig. 1d) in the DMPC/DHPC bicelles ([DMPC]/[DHPC] = 3) aligned with their normal perpendicular to the magnetic field. The simulated PISA wheels with varied tilt angles θ (0–70°) are overlaid onto the spectra. The bicelle order parameter Smol is fixed at 0.9. (c) 1H-15N SAMPI4 spectra of Pf3_24_2 in the absence (blue) and presence (red) of 2 mol% of mini-MPIase-3.
