Localization and structural analysis of the ribosomal RNA operons of Rhodobacter sphaeroides.
Nucleic acids research 19901201 24
We have identified, cloned and sequenced the three ribosomal RNA (rRNA) operons (rrn) present in the facultative photoheterotroph Rhodobacter sphaeroides. DNA sequence analysis has identified the 16S, 23S, and 5S rRNAs, two tRNAs (ile and ala) in the spacer region between the 16S and 23S rRNAs, and an f-met tRNA immediately following the 5S rRNA gene of all three operons. Physical mapping, genetic analysis, and Southern hybridization data indicate that rrnA is contained on a large chromosome and ...[more]

Project description:In Rhodobacter sphaeroides, MreB, MreC, MreD, PBP2, and RodA are encoded at the same locus. The localizations of PBP2, MreB, and MreC, which have all been implicated in the synthesis of the peptidoglycan layer, were investigated under different growth conditions to gain insight into the relationships between these proteins. Immunofluorescence microscopy showed that PBP2 localized to specific sites at the midcell of elongating cells under both aerobic and photoheterotrophic conditions. Visualizing PBP2 at different stages of the cell cycle showed that in elongating cells, PBP2 was found predominately at the midcell, with asymmetric foci and bands across the cell. PBP2 remained at midcell until the start of septation, after which it moved to midcell of the daughter cells. Deconvolution and three-dimensional reconstructions suggested that PBP2 forms a partial ring at the midcell of newly divided cells and elongated cells, while in septating cells, partial PBP2 rings were present at one-quarter and three-quarter positions. Due to the diffraction limits of light microscopy, these partial rings could represent unresolved helices. Colocalization studies showed that MreC always colocalized with PBP2, while MreB colocalized with PBP2 only during elongation; during septation, MreB remained at the septation site, whereas PBP2 relocalized to the one-quarter and three-quarter positions. These results suggest that PBP2 and MreC are involved in peptidoglycan synthesis during elongation and that this occurs at specific sites close to midcell in R. sphaeroides.

Project description:UnlabelledRhodobacter sphaeroides is a free-living alphaproteobacterium that contains two clusters of functional flagellar genes in its genome: one acquired by horizontal gene transfer (fla1) and one that is endogenous (fla2). We have shown that the Fla2 system is normally quiescent and under certain conditions produces polar flagella, while the Fla1 system is always active and produces a single flagellum at a nonpolar position. In this work we purified and characterized the structure and analyzed the composition of the Fla2 flagellum. The number of polar filaments per cell is 4.6 on average. By comparison with the Fla1 flagellum, the prominent features of the ultra structure of the Fla2 HBB are the absence of an H ring, thick and long hooks, and a smoother zone at the hook-filament junction. The Fla2 helical filaments have a pitch of 2.64 μm and a diameter of 1.4 μm, which are smaller than those of the Fla1 filaments. Fla2 filaments undergo polymorphic transitions in vitro and showed two polymorphs: curly (right-handed) and coiled. However, in vivo in free-swimming cells, we observed only a bundle of filaments, which should probably be left-handed. Together, our results indicate that Fla2 cell produces multiple right-handed polar flagella, which are not conventional but exceptional.ImportanceR. sphaeroides possesses two functional sets of flagellar genes. The fla1 genes are normally expressed in the laboratory and were acquired by horizontal transfer. The fla2 genes are endogenous and are expressed in a Fla1(-) mutant grown phototrophically and in the absence of organic acids. The Fla1 system produces a single lateral or subpolar flagellum, and the Fla2 system produces multiple polar flagella. The two kinds of flagella are never expressed simultaneously, and both are used for swimming in liquid media. The two sets of genes are certainly ready for responding to specific environmental conditions. The characterization of the Fla2 system will help us to understand its role in the physiology of this microorganism.

Project description:In this study, the in vivo function and properties of two cytochrome c maturation proteins, CcmF and CcmH from Rhodobacter sphaeroides, were analyzed. Strains lacking CcmH or both CcmF and CcmH are unable to grow under anaerobic conditions where c-type cytochromes are required, demonstrating their critical role in the assembly of these electron carriers. Consistent with this observation, strains lacking both CcmF and CcmH are deficient in c-type cytochromes when assayed under permissive growth conditions. In contrast, under permissive growth conditions, strains lacking only CcmH contain several soluble and membrane-bound c-type cytochromes, albeit at reduced levels, suggesting that this bacterium has a CcmH-independent route for their maturation. In addition, the function of CcmH that is needed to support anaerobic growth can be replaced by adding cysteine or cystine to growth media. The ability of exogenous thiol compounds to replace CcmH provides the first physiological evidence for a role of this protein in thiol chemistry during c-type cytochrome maturation. The properties of R. sphaeroides cells containing translational fusions between CcmF and CcmH and either Escherichia coli alkaline phosphatase or beta-galactosidase suggest that they are each integral cytoplasmic membrane proteins with their presumed catalytic domains facing the periplasm. Analysis of CcmH shows that it is synthesized as a higher-molecular-weight precursor protein with an N-terminal signal sequence.

Project description:The R481 residue in cytochrome c oxidase from Rhodobacter sphaeroides forms hydrogen bonds with the propionate groups of both heme a and heme a(3). It has been postulated that R481 is the proton loading site in the proton exit pathway essential for proton translocation. A recent functional study showed that the mutations of R481 to His, Leu and Gln cause the reduction of the activity to approximately 5-18% of the native level, and the absence of proton pumping in R481Q but retention of approximately 40% efficiency in R481H and R481L (H.J. Lee, L. Ojemyr, A. Vakkasoglu, P. Brzezinski and R. B. Gennis, manuscript submitted). To decipher the molecular mechanism underlying the perturbed functionalities, we have used resonance Raman spectroscopy to examine the structural properties of the three mutants. The data show that the frequencies of the formyl CO stretching modes of both the heme a and a(3) in the mutants are characteristic of formyl groups exposed to an aqueous environment, indicating that the mutations disrupt the native H-bonding interaction between the formyl group of heme a and R52, as well as the hydrophobic environment surrounding the formyl group of heme a(3). In addition to the change in the environments of heme a and a(3), the Raman data show that the mutations induce a partial conversion of the heme a(3) from a high-spin to a low-spin state, suggesting that the mutations are associated with the rearrangement of the Cu(B)-heme a(3) binuclear center. The Raman results reported here demonstrate that R481 plays a critical role in supporting efficient proton pumping, by holding the heme groups in a proper environment.

Project description:Rhodobacter sphaeroides chemotaxis is significantly more complex than that of enteric bacteria. Rhodobacter sphaeroides has multiple copies of chemotaxis genes (two cheA, one cheB, two cheR, three cheW, five cheY but no cheZ), controlling a single 'stop-start' flagellum. The growth environment controls the level of expression of different groups of genes. Tethered cell analysis of mutants suggests that CheY(4) and CheY(5) are the motor-binding response regulators. The histidine protein kinase CheA(2) mediates an attractant ('normal') response via CheY(4), while CheA(1) and CheY(5) appear to mediate a repellent ('inverted') response. CheY(3) facilitates signal termination, possibly acting as a phosphate sink, although CheY(1) and CheY(2) can substitute. The normal and inverted responses may be initiated by separate sets of chemoreceptors with their relative strength dependent on growth conditions. Rhodobacter sphaeroides may use antagonistic responses through two chemosensory pathways, expressed at different levels in different environments, to maintain their position in a currently optimum environment. Complex chemotaxis systems are increasingly being identified and the strategy adopted by R.sphaeroides may be common in the bacterial kingdom.

Project description:Structural genes encoding Calvin cycle enzymes in Rhodobacter sphaeroides are duplicated and organized within two physically distinct transcriptional units, the form I and form II cbb operons. Nucleotide sequence determination of the region upstream of the form I operon revealed a divergently transcribed open reading frame, cbbR, that showed significant similarity to the LysR family of transcriptional regulatory proteins. Mutants containing an insertionally inactivated cbbR gene were impaired in photoheterotrophic growth and completely unable to grow photolithoautotrophically with CO2 as the sole carbon source. In the cbbR strain, expression of genes within the form I operon was completely abolished and that of the form II operon was reduced to about 30% of the wild-type level. The cloned cbbR gene complemented the mutant for wild-type growth characteristics, and normal levels of ribulose 1,5-bisphosphate carboxylase/oxygenase (RubisCO) were observed. However, rocket immunoelectrophoresis revealed that the wild-type level of RubisCO was due to overexpression of the form II enzyme, whereas expression of the form I RubisCO was 10% of that of the wild-type strain. The cbbR insertional inactivation did not appear to affect aerobic expression of either CO2 fixation operon, but preliminary evidence suggests that the constitutive expression of the form II operon observed in the cbbR strain may be subject to repression during aerobic growth.

Project description:BackgroundThe genus Rhodobacter contains purple nonsulfur bacteria found mostly in freshwater environments. Representative strains of two Rhodobacter species, R. capsulatus and R. sphaeroides, have had their genomes fully sequenced and both have been the subject of transcriptional profiling studies. Gene co-expression networks can be used to identify modules of genes with similar expression profiles. Functional analysis of gene modules can then associate co-expressed genes with biological pathways, and network statistics can determine the degree of module preservation in related networks. In this paper, we constructed an R. capsulatus gene co-expression network, performed functional analysis of identified gene modules, and investigated preservation of these modules in R. capsulatus proteomics data and in R. sphaeroides transcriptomics data.ResultsThe analysis identified 40 gene co-expression modules in R. capsulatus. Investigation of the module gene contents and expression profiles revealed patterns that were validated based on previous studies supporting the biological relevance of these modules. We identified two R. capsulatus gene modules preserved in the protein abundance data. We also identified several gene modules preserved between both Rhodobacter species, which indicate that these cellular processes are conserved between the species and are candidates for functional information transfer between species. Many gene modules were non-preserved, providing insight into processes that differentiate the two species. In addition, using Local Network Similarity (LNS), a recently proposed metric for expression divergence, we assessed the expression conservation of between-species pairs of orthologs, and within-species gene-protein expression profiles.ConclusionsOur analyses provide new sources of information for functional annotation in R. capsulatus because uncharacterized genes in modules are now connected with groups of genes that constitute a joint functional annotation. We identified R. capsulatus modules enriched with genes for ribosomal proteins, porphyrin and bacteriochlorophyll anabolism, and biosynthesis of secondary metabolites to be preserved in R. sphaeroides whereas modules related to RcGTA production and signalling showed lack of preservation in R. sphaeroides. In addition, we demonstrated that network statistics may also be applied within-species to identify congruence between mRNA expression and protein abundance data for which simple correlation measurements have previously had mixed results.

Project description:MreB is thought to be a bacterial actin homolog that defines the morphology of rod-shaped bacteria. Rhodobacter sphaeroides changes shape, from a rod to coccobacillus, and undergoes extensive cytoplasmic membrane invagination when it switches from aerobic to photoheterotrophic growth. The role of MreB in defining R. sphaeroides shape was therefore investigated. Attempts at deleting or insertionally inactivating mreB were unsuccessful under all growth conditions. Immunofluorescence microscopy showed MreB localized to mid-cell in elongating cells under both aerobic and photoheterotrophic conditions. Three-dimensional reconstruction showed that MreB formed a ring at mid-cell. MreB remained at mid-cell as septation began but localized to new sites in the daughter cells before the completion of septation. MreB localized to putative septation sites in cephalexin-treated filamentous cells. Genomic single-copy mreB was replaced with gfp-mreB, and green fluorescent protein (GFP)-MreB localized in the same pattern, as seen with immunofluorescence microscopy. Some of the cells expressing GFP-MreB were abnormal, principally displaying an increase in cell width, suggesting that the fusion was not fully functional in all cells. GFP-MreB localized to swellings at mid-cell in cells treated with the penicillin-binding protein 2 inhibitor amdinocillin. These data suggest that MreB is essential in R. sphaeroides, performing a role at mid-cell in elongating cells, and in early septation, putatively in the cytoplasmic control of the peptidoglycan synthetic complexes.

Project description:The genome of Rhodobacter sphaeroides encodes the components of two distinct pathways for salvaging cobinamide (Cbi), a precursor of adenosylcobalamin (AdoCbl, coenzyme B(12)). One pathway, conserved among bacteria, depends on a bifunctional kinase/guanylyltransferase (CobP) enzyme to convert adenosylcobinamide (AdoCbi) to AdoCbi-phosphate (AdoCbi-P), an intermediate in de novo AdoCbl biosynthesis. The other pathway, of archaeal origin, depends on an AdoCbi amidohydrolase (CbiZ) enzyme to generate adenosylcobyric acid (AdoCby), which is converted to AdoCbi-P by the AdoCbi-P synthetase (CobD) enzyme. Here we report that R. sphaeroides strain 2.4.1 synthesizes AdoCbl de novo and that it salvages Cbi using both of the predicted Cbi salvaging pathways. AdoCbl produced by R. sphaeroides was identified and quantified by high-performance liquid chromatography and bioassay. The deletion of cobB (encoding an essential enzyme of the de novo corrin ring biosynthetic pathway) resulted in a strain of R. sphaeroides that would not grow on acetate in the absence of exogenous corrinoids. The results from a nutritional analysis showed that the presence of either CbiZ or CobP was necessary and sufficient for Cbi salvaging, that CbiZ-dependent Cbi salvaging depended on the presence of CobD, and that CobP-dependent Cbi salvaging occurred in a cbiZ(+) strain. Possible reasons why R. sphaeroides maintains two distinct pathways for Cbi salvaging are discussed.
