A solved puzzle: The structure of the seven-transmembrane-helix proton pump proteorhodopsin obtained by solution NMR spectroscopy is based on NOE data combined with distance restraints derived from paramagnetic relaxation enhancement (see picture). Restraints from residual dipolar couplings improved the structural accuracy.
