PubMed Abstract: The light-harvesting complexes II (LH-2s) are integral membrane proteins that form ring-like structures, oligomers of alpha beta-heterodimers, in the photosynthetic membranes of purple bacteria. They contain a large number of chromophores organized optimally for light absorption and rapid light energy migration. Recently, the structure of the nonameric LH-2 of Rhodopseudomonas acidophila has been determined; we report here the crystal structure of the octameric LH-2 from Rhodospirillum molischianum. The unveiling of similarities and differences in the architecture of these proteins may provide valuable insight into the efficient energy transfer mechanisms of bacterial photosynthesis.
