(Submitter supplied) The facultatively photosynthetic bacterium Rhodobacter sphaeroides harbors an unusual LOV (light, oxygen, voltage) domain protein, RsLOV. While showing a characteristic photocycle, the protein misses a C - terminal output domain, similar to PpSB2 in Pseudomonas putida. Oxygen tension and light quantity are the two main responsible factors controlling the expression of photosynthesis genes in Rhodobacter sphaeroides. more...

(Submitter supplied) Exposure to oxygen and light generates photooxidative stress by the bacteriochlorophyll a mediated formation of singlet oxygen (1O2) in the facultative photosynthetic bacterium Rhodobacter sphaeroides. We have identified SorY as an sRNA, which is induced under several stress conditions and confers increased resistance against 1O2. SorY by direct interaction decreases the levels of takP mRNA, encoding a TRAP-T transporter. more...

(Submitter supplied) To learn more about the function of SorX, we constructed an over-expression strain. For this purpose, the sorX gene together with its 28-bp upstream region was cloned into the over-expression vector pRK4352 and expressed in the R. sphaeroides wild-type 2.4.1 background. The corresponding strain consequently exhibits a SorX over-expression that is driven by the constitutive 16S rRNA (RSP_4352) promoter. more...

(Submitter supplied) Global transcriptome analyses at different stages of growth were applied to monitor growth phase-dependent gene expression in the alpha-proteobacterium Rhodobacter sphaeroides. Cultures with low aeration, which underwent strong changes in levels of dissolved oxygen during growth, were compared to aerated cultures, which showed little variation in levels of dissolved oxygen. Cells were in stationary phase for 12 h or for 57 h before dilution into fresh medium. more...
