The application of two-dimensional PDLF spectroscopy to non-helical residues of membrane proteins in magnetically aligned phospholipid bilayers. (A) The spectrum was acquired on the membrane-bound form of the Pf1 coat protein. The inset shows the indirect dimension time evolution of the signal from residue A46, which has a 15N chemical shift of 138 ppm and is marked in the spectrum. Its line width is noted near the resonance. (B) The spectrum was acquired on MerFm “flipped” bicelles by the additional of lanthanide ion as described previously [40,47,48]. The non-helical region of MerFm displays single-site resolution in the PDLF spectrum.
