The O-17-'diluted' glycine-14 sites in a phospholemman (PLM) transmembrane domain protein are characterized by solid-state O-17 NMR spectroscopy. The PLM transmembrane domain is an a-helical tetramer unit of four 28-residue peptides and is rigidly embedded in a bilayer where each a-helix has an average tilt of 7.3 degrees against the membrane normal. The PLM sample investigated here consists of a high lipid/peptide molar ratio (25: 1) with one glycine residue in each helix enriched to
