Narrow single-line resonances are observed from 15N labeled sites in the trans-membrane helix of the channel-forming domain of the protein Vpu from HIV-1 in phospholipid bilayers with their normals at angles of 0 degrees, 20 degrees, 40 degrees, and 90 degrees, and bicelles with their normals at angles of 0 degrees and 90 degrees with respect to the direction of the applied magnetic field. This could only occur if the entire polypeptide undergoes rotational diffusion about the bilayer normal. Comparisons between experimental and simulated spectra are consistent with a rotational diffusion coefficient (DR) of approximately 10(5)s-1.
