The solution structure of the PufX polypeptide from Rhodobacter sphaeroides.

PubMed Abstract: 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.
