What is The Six Fold Symmetry of the B880 Light-Harvesting Complex and the Structure of the Photosynthetic Membranes of Rhodopseudomonas marina about?
The reaction center free light-harvesting core complex of Rp. marina was purified by DEAE 52 ion exchange chromatography in the presence of the detergent OG. The protein complex was crystallised by microdialysis yielding two-dimensional crystals with a diameter of up to 10μπΊ. The crystals were negatively stained with uranyl acetate or prepared in vitrified ice and electron micrographs were taken. They exhibited a hexagonal lattice with a lattice constant of 102 ± 3 A. The optical diffraction pattern of the best ordered areas of electron micrographs showed spots up to a resolution of 29 A. Image processing revealed a six fold symmetry of the ring like B880-complex.The protein ring is hexagonal with one subunit in each corner of the hexagon and two subunits forming the connection site to the neighbouring B880-complex in the crystal. In freeze fracture preparations of whole cells the intra-cytoplasmic photosynthetic membranes are seen to be organised into large stacks that affect the organisation of the photosynthetic complexes. Most notably, the stacked membrane regions exhibit hexagonally packed photosynthetic complexes with a repeat of ~ 100 A, which is very similar to the lattice
