TranscriptomicsExpression data from H2-producing Rhodobacter sphaeroides cultures fed different organic substrates
Rhodobacter sphaeroides produces hydrogen gas (H2) via its nitrogenase enzyme during photoheterotrophic growth under nitrogen-limited conditions. We find that cells produce different amounts of H2 and show different growth rates, depending on the organic substrate provided (lactate, succinate, gluc...

TranscriptomicsDigging deeper into the PpsR regulon of Rhodobacter sphaeroides
The expression of genes involved in photosystem development in Rhodobacter sphaeroides is dependent upon three major regulatory networks: FnrL, the PrrBA two-component system and the AppA-PpsR pathway. A PrrA- mutant strain of R. sphaeroides is unable to develop under photosynthetic conditions, but ...

ProteomicsConfirmation of the subunit composition of Rhodobacter sphaeroides cytochrome bc1 complex isolated in styrene maleic acid nanodiscs.
The purple α-proteobacterium Rhodobacter sphaeroides is a long-established model organism owing to its ability to switch between aerobic, anaerobic and phototrophic metabolism. This organism is also of great interest because of its phylogenetic relationship with the bacterial progenitor of the mitoc...

ProteomicsStructural characterization of the reaction center-light harvesting 1-PufXY complex from Rhodobacter sphaeroides
Photosynthesis in purple bacteria, represented by Rhodobacter sphaeroides as a long-established model organism, utilizes a protein-cofactor complex to capture solar energy. This complex is embedded in specialized spherical membrane structures and comprises a central reaction center (RC) encircled by...

TranscriptomicsRpoE regulon in Rhodobacter sphaeroides
In Rhodobacter sphaeroides a transcriptional response to the reactive oxygen species singlet oxygen is controlled by the group IV sigma factor RpoE and the anti-sigma factor ChrR. In this study, we integrated various large datasets to identify genes within the singlet oxygen stress response that con...

TranscriptomicsFnrL regulon in Rhodobacter sphaeroides
In this study, we performed a ChIP-chip experiment to determine the regulon of FnrL in Rhodobacter sphaeroides. We grew R. sphaeroides under anaerobic photosnthetic conditions, in which FnrL is expected to bind DNA and contol gene expression, and immuno-precipitated FnrL, but also sigma70 and the Be...

TranscriptomicsRpoHI and RpoHII regulons in Rhodobacter sphaeroides 2.4.1 from gene expression profiling
In this study, we performed expression profiling experiments to determine the respective regulons of RpoHI and RpoHII in Rhodobacter sphaeroides. We grew R. sphaeroides in aerobic conditions and induced either proteins ectopically and compared the global gene expression profiles. The expression prof...
