PufX organizes the photosynthetic reaction centre-light harvesting complex, 1 (RC-LH1) core complex of Rhodobacter sphaeroides and facilitates, quinol/quinone exchange between the RC and cytochrome bc(1) complexes. The, structure of PufX in organic solvent reveals two hydrophobic helices, flanked by unstructured termini and connected by a helical bend. The, proposed location of basic residues and tryptophans at the membrane, interface orients the C-terminal helix along the membrane normal, with the, GXXXG motifs in positions unsuitable as direct drivers of dimerisation of, the RC-LH1 complex. The N-terminal helix is predicted to extend, approximately 40 Anggstrom along the membrane interface.
