Crystal structure of an integral membrane light-harvesting complex from photosynthetic bacteria
The crystal structure of the light-harvesting antenna complex (LH2) from Rhodopseudomonas acidophila strain 10050 shows that the active assembly consists of two concentric cylinders of helicalExpand
Crystal Structure of the RC-LH1 Core Complex from Rhodopseudomonas palustris
A break in the crystal structure of the reaction center–light harvesting 1 (RC–LH1) core complex from Rhodopseudomonas palustris may provide a portal through which UQB can transfer electrons to cytochrome b/c1. Expand
The architecture and function of the light-harvesting apparatus of purple bacteria: from single molecules to in vivo membranes
The structures of the two major integral membrane pigment complexes, the RC–LH1 ‘core’ and LH2 complexes, which together make up the light-harvesting system present in typical purple photosynthetic bacteria are described. Expand
The structure and thermal motion of the B800-850 LH2 complex from Rps.acidophila at 2.0A resolution and 100K: new structural features and functionally relevant motions.
The calculated energy changes indicate that there may be significant contributions to inter-pigment energy interactions from molecular displacements and these may be of importance to photosynthetic energy transfer. Expand
Carotenoids in photosynthesis.
Evidence is presented as to how the carotenoids are organized within both portions of the photosynthetic unit (the light harvesting antenna and the reaction centre) and how they discharge both their functions. Expand
Structural details of an interaction between cardiolipin and an integral membrane protein.
This study provides the first, to the authors' knowledge, high-resolution x-ray crystal structure for cardiolipin, a key light-driven electron transfer protein complex found in the cytoplasmic membrane of photosynthetic bacteria. Expand
How carotenoids function in photosynthetic bacteria.
The behavior of carotenoids in photosynthetic bacterial reaction centers and light-harvesting complexes is correlated with data from experiments carried out on carOTenoids and model systems in vitro. Expand
Complete DNA sequence, specific Tn5 insertion map, and gene assignment of the carotenoid biosynthesis pathway of Rhodobacter sphaeroides
This study provides gene sequences and assignments based upon a comprehensive structural, spectroscopic, and biochemical analysis of a range of carotenoid biosynthetic mutants; in each mutation, the point of Tn5 insertion is determined accurate to 1 bp on the gene cluster. Expand
How Photosynthetic Bacteria Harvest Solar Energy
The past several years have seen dramatic progress in our understanding of the reactions taking place in the early events of photosynthesis. This has been in large part due to research involvingExpand
