BMC Genomics 2011, 12:334 http://www.biomedcentral.com/1471-2164/12/334 RESEARCHARTICLE Open Access Complete genome sequence of the filamentous anoxygenic phototrophic bacterium Chloroflexus aurantiacus Kuo-Hsiang Tang1, Kerrie Barry2, Olga Chertkov3, Eileen Dalin2, Cliff S Han3, Loren J Hauser4, Barbara M Honchak1, Lauren E Karbach1,7, Miriam L Land4, Alla Lapidus5, Frank W Larimer4, Natalia Mikhailova5, Samuel Pitluck2, Beverly K Pierson6 and Robert E Blankenship1* Abstract Background: Chloroflexus aurantiacus is a thermophilic filamentous anoxygenic phototrophic (FAP) bacterium, and can grow phototrophically under anaerobic conditions or chemotrophically under aerobic and dark conditions. According to 16S rRNA analysis, Chloroflexi species are the earliest branching bacteria capable of photosynthesis, and Cfl. aurantiacus has been long regarded as a key organism to resolve the obscurity of the origin and early evolution of photosynthesis. Cfl. aurantiacus contains a chimeric photosystem that comprises some characters of green sulfur bacteria and purple photosynthetic bacteria, and also has some unique electron transport proteins compared to other photosynthetic bacteria. Methods: The complete genomic sequence of Cfl. aurantiacus has been determined, analyzed and compared to the genomes of other photosynthetic bacteria. Results: Abundant genomic evidence suggests that there have been numerous gene adaptations/replacements in Cfl. aurantiacus to facilitate life under both anaerobic and aerobic conditions, including duplicate genes and gene clusters for the alternative complex III (ACIII), auracyanin and NADH:quinone oxidoreductase; and several aerobic/ anaerobic enzyme pairs in central carbon metabolism and tetrapyrroles and nucleic acids biosynthesis. Overall, genomic information is consistent with a high tolerance for oxygen that has been reported in the growth of Cfl.

Abstract We report here a detailed analysis of the proteome adjustments that accompany chromoplast differentiation from chloroplasts during bell-pepper fruit ripening. While the two photosystems are disassembled and their constituents degraded, the cytochrome b6f complex, the ATPase complex as well as Calvin cycle enzymes are maintained at high levels up to fully mature chromoplasts.

    Thesis C11orf83, a mitochondrial cardiolipin-binding protein involved in bc1 complex assembly and supercomplex stabilization DESMURS-ROUSSEAU, Marjorie Abstract Cette thèse a permis d'identifier C11orf83, désormais appelé UQCC3, comme étant une protéine mitochondriale ancrée dans la membrane interne. Nous avons constaté l'implication de C11orf83 dans l'assemblage du complexe III de la chaîne respiratoire via la stabilisation du complexe intermédiaire MT-CYB/UQCRB/UQCRQ. Nous avons également prouvé que C11orf83 était associée avec le dimère de complexe III et était détectée dans le supercomplexe III2/IV. Son absence induit une baisse significative de ce supercomplexe et du respirasome (I/III2/IV). La capacité de C11orf83 de lier les cardiolipines, connues pour être impliquées dans la formation et la stabilisation de ces supercomplexes, pourrait expliquer ces résultats. Ainsi, ce travail de thèse en lien avec une récente étude clinique mettant en évidence une déficience du complexe III chez un patient atteint d'une mutation du gène C11orf83 (Wanschers et al., 2014) permet d'améliorer les connaissances sur l'assemblage du complexe III et la compréhension d'une maladie mitochondriale.

  • Time-Independent Structure of the Cytochrome B6f Complex† William A
    Evolution of Photosynthesis: Time-Independent Structure of the Cytochrome b6f Complex† William A. Cramer,* Huamin Zhang, Jiusheng Yan, Genji Kurisu,‡ and Janet L. Smith Department of Biological Sciences, Lilly Hall of Life Sciences, 915 West State Street, Purdue UniVersity, West Lafayette, Indiana 47907-2054 ReceiVed March 22, 2004; ReVised Manuscript ReceiVed April 7, 2004 ABSTRACT: Structures of the cytochrome b6f complex obtained from the thermophilic cyanobacterium Mastigocladus laminosus and the green alga Chlamydomonas reinhardtii, whose appearance in evolution is separated by 109 years, are almost identical. Two monomers with a molecular weight of 110 000, containing eight subunits and seven natural prosthetic groups, are separated by a large lipid-containing “quinone exchange cavity”. A unique heme, heme x, that is five-coordinated and high-spin, with no strong field ligand, occupies a position close to intramembrane heme bn. This position is filled by the n-side bound quinone, Qn, in the cytochrome bc1 complex of the mitochondrial respiratory chain. The structure and position of heme x suggest that it could function in ferredoxin-dependent cyclic electron transport as well as being an intermediate in a quinone cycle mechanism for electron and proton transfer. The significant differences between the cyanobacterial and algal structures are as follows. (i) On the n-side, a plastoquinone molecule is present in the quinone exchange cavity in the cyanobacterial complex, and a sulfolipid is bound in the algal complex at a position corresponding to a synthetic DOPC lipid molecule in the cyanobacterial complex. (ii) On the p-side, in both complexes a quinone analogue inhibitor, TDS, passes through a portal that separates the large cavity from a niche containing the Fe2S2 cluster.

  • Overexpression of the Rieske Fes Protein of the Cytochrome B6f

Their CO2 concentrating mechanism operating between mesophyll and bundle sheath cells increases CO2 partial pressure at the site of Rubisco and hence photosynthetic efficiency. Electron transport chains in both cell types supply ATP and NADPH for C4 photosynthesis. Since Cytochrome b6f is a key point of control of electron transport in C3 plants, we constitutively overexpressed the Rieske FeS subunit in Setaria viridis to study the effects on C4 photosynthesis. Rieske FeS overexpression resulted in a higher content of Cytochrome b6f in both mesophyll and bundle sheath cells without marked changes in abundances of other photosynthetic complexes and Rubisco. Plants with higher Cytochrome b6f abundance showed better light conversion efficiency in both Photosystems and could generate higher proton-motive force across the thylakoid membrane.
