The NtrYX two-component system regulates the bacterial cell envelope

(Submitter supplied) To investigate the R. sphaeroides NtrYX two component system on RNA transcript levels, we used global RNA sequencing (RNA-seq) to compare transcript abundance in parent and DntrYX strains grown under aerobic conditions. Our previous studies were performed in strains deficient at synthesizing the polyhydroxybutyrate, so we used strains D0382 and DNtrYXD0382, herein referred to as parent and DntrYX, respectively. more...

Defining the transcriptional regulon of ChvI in Caulobacter crescentus

(Submitter supplied) We sought to define the transcriptional regulon of the ChvI response regulator in Caulobacter crescentus. This study compares gene expression between ∆chvI cells and cells overexpressing the constitutively-active chvI(D52E) mutant. Our work provides a global view of the genes directly and indirectly regulated by the ChvGI two-component system in C. crescentus.

The Essential Rhodobacter sphaeroides RSP1056-RSP0847 (CenKR) Two-Component System Regulated Tol-Pal and Cell Envelope Biosynthesis

(Submitter supplied) To determine the regulon of RSP1056-RSP0847 TCS (response regulator with DNA-binding domains) we used ChIP-seq to determine the genomic occupancy of RSP0847 in strains with a hyperactive (RSP0847(D56E)), WT, and low activity (ΔRSP1056, RSP0847(D56A)) TCS. We then correlated cenR binding sites with changes in global gene expression between WT and strains with a hyperactive (RSP1056(D56E)) or low activity (ΔRSP1056, RSP0847(D56A)) TCS in RNA-seq experiments.

Growth-phase dependent gene regulation in the alpha-proteobacterium Rhodobacter sphaeroides

(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...

IscR of Rhodobacter sphaeroides functions as repressor of genes for iron-sulphur metabolism and represents a new type of iron-sulphur binding protein

(Submitter supplied) Iron-sulphur (Fe-S) clusters are ensembles of iron and sulphide centres. They are found in all life forms and are important components of many enzymes involved in diverse cellular processes, including respiration, DNA synthesis or gene regulation. However, the increase in oxygen after the emergence of oxygenic photosynthesis created a threat to Fe–S proteins and, consequently, to the organisms relying on them. more...

Transcriptome response to nitrosative stress in Rhodobacter sphaeroides 2.4.1

(Submitter supplied) DNA microarray analysis was employed to investigate the transcriptome response to nitrosative stress in a non-denitrifying facultative photosynthetic bacterium Rhodobacter sphaeroides 2.4.1. We focused on the role played by a nitric oxide-response transcriptional regulator NnrR in the response. The transcriptome profiles of R. sphaeroides 2.4.1 and its nnrR mutant before and after exposure to nitrosating agents S-nitrosoglutathione (GSNO) or sodium nitroprusside (SNP) under semiaerobic conditions were analyzed.

Expression data from Burkholderia multivorans mucoid and nonmucoid isolates

(Submitter supplied) Burkholderia multivorans comprises opportunistic bacteria infecting hosts such as cystic fibrosis (CF) patients. Bcc long-term infection of CF patient airways has been associated with emergence of phenotypic variation including the mucoid-to-nonmucoid colony morphotype. Here we studied three Burkholderia multivorans clonal isolates (mucoid D2095 (BM11L), and nonmucoid D2214G and D2214P) and a laboratory nonmucoid variant (BM11L-nmv1) obtained under prolonged stationary phase. more...

Rhodobacter sphaeroides 2.4.1 pRKSorX144 versus pRK415 under singlet oxygen stress.

(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...

A unique mode of cross regulation in a cell envelope stress signaling system [RNA-seq]

(Submitter supplied) A multi-layered structure known as the cell envelope separates the controlled interior of Gram-negative bacteria from a fluctuating physical and chemical environment. Transcription of genes that determine cell envelope structure and function is commonly controlled by a class of environmental regulators known as two-component signal transduction systems (TCS), which are comprised of 1) sensor histidine kinases and 2) response regulators. more...
