Abstract (sommario):
Four strains (JA310T, JA531T, JA447 and JA490) of red to reddish brown pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from soil and freshwater sediment samples from different geographical regions of India. All strains contained bacteriochlorophyll a and carotenoids of the spirilloxanthin series. The major cellular fatty acid of strains JA310T and JA531T was C18 : 1ω7c, the quinone was Q-10 and polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, an aminohopanoid and an unidentified aminolipid. Phylogenetic analysis based on 16S rRNA gene sequences showed that all strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA531T, JA447 and JA490 were genotypically (>80 % related based on DNA–DNA hybridization) and phenotypically closely related to each other and the three strains were distinct from strain JA310T (33 % related). Furthermore, all four strains had less than 48 % relatedness (DNA–DNA hybridization) with type strains of members of the genus Rhodopseudomonas , i.e. Rhodopseudomonas palustris ATCC 17001T, Rhodopseudomonas faecalis JCM 11668T and Rhodopseudomonas rhenobacensis DSM 12706T. The genomic DNA G+C contents of strains JA310T and JA531T were 63.8 and 62.4 mol%, respectively. On the basis of phenotypic, chemotaxonomic and molecular genetic evidence, it is proposed that strains JA310T ( = NBRC 106083T = KCTC 5839T) and JA531T ( = NBRC 107575T = KCTC 5841T) be classified as the type strains of two novel species of the genus Rhodopseudomonas , Rhodopseudomonas parapalustris sp. nov. and Rhodopseudomonas harwoodiae sp. nov., respectively. In addition, we propose that strain DSM 123T ( = NBRC 100419T) represents a novel species, Rhodopseudomonas pseudopalustris sp. nov., since this strain differs genotypically and phenotypically from R. palustris ATCC 17001T and other members of the genus Rhodopseudomonas . An emended description of R. palustris is also provided.

Abstract (sommario):
In this study, we isolated a strain of photosynthetic bacteria from landscape water located in Southwest University, Chongqing, China, and named it Smobiisys501. Smobiisys501 was Rhodopseudomonas sp. according to its cell morphological properties and absorption spectrum analysis of living cells. The analysis of the 16S rDNA amplification sequence with specific primers of photosynthetic bacteria showed that the homology between Smobiisys501 and Rhodopseudomonas sp. was 100%, and the alignment results of protein sequences of the bacterial chlorophyll Y subunit showed that Smobiisys501 and Rhodopseudomonas palustris were the most similar, with a similarity of more than 92%. However, Smobiisys501 could not utilize glucose and mannitol as a carbon source and had a low fatty acid content, which were different from the related strains of the genus Rhodopseudomonas. Moreover, the DNA-DNA relatedness was only 42.2 ± 3.3% between Smobiisys501 and the closest strain Rhodopseudomonas palustris. Smobiisys501 grew optimally at 30 °C and pH 7.0 in the presence of yeast extract, and it could efficiently remove ammonium (99.67% removal efficiency) from synthetic ammonium wastewater. All the results indicated that Smobiisys501 was a novel species of Rhodopseudomonas, with the ability to remove ammonium.

Abstract (sommario):
The genus Rhodopseudomonas is known for its versatile metabolic capabilities and has been proposed to be used in a wide variety of innovative applications, ranging from biohydrogen and electricity production, bioremediation and as biostimulant in agriculture. Here, we report the isolation, characterization and genome sequence analysis of a novel Rhodopseudomonas species, strain HC1, isolated from the Hell Creek urban native restoration area. Whole genome-based analysis, average nucleotide identity (ANI) comparison, and growth characteristics identified this isolate as a new species of the Rhodopseudomonas genus, for which we propose the name Rhodopseudomonas infernalis sp. nov. Besides containing several nitrogenases for nitrogen fixation and hydrogen production, the HC1 genome encodes a unique gene cluster, not found in any other Rhodopseudomonas species, which encodes genes for the degradation of yet-unidentified aromatic PCB-type chemicals with potentially interesting biotechnological applications. The genomic features of Rps. infernalis HC1 indicate that it plays a positive role in the degradation of anthropogenic substances and aids the restoration of the Hell Creek watershed by contributing to N2 and carbon fixation and plant growth; however, the genome also contains several antibiotic resistance genes, indicating a broad range of antibiotic resistance in this environmental isolate.

Abstract (sommario):
Two strains (JA575T and JA576T) of orange- to pink-pigmented, rod-shaped, motile and budding phototrophic bacteria were isolated from paddy soils. Both strains contained bacteriochlorophyll a and carotenoids of spirilloxanthin series. Both strains had C18 : 1ω7c as the major cellular fatty acid, ubiquinone-10 (Q10) as the main quinone, and diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and phosphatidylcholine as polar lipids. Phylogenetic analysis on the basis of 16S rRNA gene sequences showed that both strains clustered with species of the genus Rhodopseudomonas in the class Alphaproteobacteria . Strains JA575T and JA576T were genotypically (<35 % DNA–DNA relatedness) and phenotypically distinct from each other. Further, both strains showed less than 48 % DNA–DNA relatedness with the type strains of all recognized species of the genus Rhodopseudomonas . The molecular evidence is supported by phenotypic evidence. It is proposed that strains JA575T and JA576T be classified as representing two novel species of the genus Rhodopseudomonas with the species names Rhodopseudomonas pentothenatexigens sp. nov. and Rhodopseudomonas thermotolerans sp. nov., respectively. The type strains of the proposed novel species are JA575T ( = NBRC 108862T = KCTC15143T) and JA576T ( = NBRC 108863T = KCTC 15144T), respectively.

Abstract (sommario):
The genus Rhodopseudomonas , containing purple nonsulfur photosynthetic Proteobacteria, has a number of strains that belong to different species, although many of them are collectively called Rhodopseudomonas palustris . The type species R. palustris and closely related species are the focus of this paper. The comparison of available genome sequences indicate that the following Rhodopseudomonas species are well recognized: R. palustris (strains ATH 2.1.6T=DSM 123T=NBRC 100419T and BisB5), Rhodopseudomonas rutila (strains R1T, DSM 126, CGA009, ATH 2.1.37, Eli 1980, ATCC 17001 and TIE1), Rhodopseudomonas pentothenatexigens JA575T and Rhodopseudomonas faecalis JCM 11668T. Other strains for which genome sequences are available are distinct from these four species. Evidence is presented that R. palustris strain ATH 2.1.6T–KCM as obtained directly from the van Niel collection by one of us (T.E.M.) is identical to the DSMZ deposit DSM 123T of ATH 2.1.6T, but not to the deposit at ATCC 17001. The amino acid sequences of the cytochromes C2 and C556 from R. palustris strain ATH 2.1.6T–KCM are in complete agreement with the translated genome sequences of R. palustris DSM 123T. In addition, the 16S rRNA gene sequence of R. palustris NBRC 100419T completely matches that of strain DSM 123T. In conclusion, the type strain of R. palustris ATH 2.1.6T is correctly represented by DSM 123T and NBRC 100419T. However, the deposit at ATCC 17001 has properties that do not conform with properties of authentic R. palustris , but rather indicate that this is a strain of R. rutila . The previously suggested assignment of the type strain of R. palustris DSM 123T to the new species R. pseudopalustris was incorrect because strain DSM 123T is the authentic type strain of R. palustris .

Abstract (sommario):
The nucleotide sequence of a 2.37 kb DNA fragment derived from cloning a total DNA digest of Rhodopseudomonas capsulata sp108 was determined. The DNA codes for a beta-lactamase, a protein showing sequence similarity to the ampR protein of Enterobacter cloacae and an unidentified open reading frame. Hybridization experiments with a probe carrying DNA from within the beta-lactamase gene suggests a chromosomal location for the coding sequences in strain sp108 and in sp109, a penicillin-sensitive revertant of sp108 in which the enzyme is not inducible. A protein-sequence comparison of the deduced amino acid sequence of the Rps. capsulata beta-lactamase indicates that it is a Class A enzyme and that its sequence can be aligned with those of the characterized beta-lactamases from Staphylococcus aureus, Bacillus licheniformis and the Escherichia coli plasmid (R-TEM enzyme), with only a few insertions or deletions. The corresponding DNA sequence is, however, characteristically rhodopseudomonad, suggesting that it is not a recently transposed gene.

Abstract (sommario):
Rhodopseudomonas palustris est une bactérie pourpre photosynthétique dont le génome, entièrement séquencé, a révélé avec surprise la présence de 6 gènes codant des bactériophytochromes. L'un d'entre eux (RpBphP1) joue un rôle primordial et inhabituel dans la synthèse du photosystème. Chez cette bactérie, trois autres bactériophytochromes (RpBphP2, 3 et 4) sont localisés à proximité d'opérons pucBA codant les polypeptides des antennes collectrices de lumière associées au photosystème. Ce travail de thèse a consisté dans un premier temps à étudier les rôles, les propriétés et les mécanismes d'action de ces 3 bactériophytochromes. Il a pu être ainsi montré que les 2 bactériophytochromes RpBphP2 et 3 agissent de concert dans le contrôle des antennes de types LH4. Cette voie de régulation implique l'action de 3 autres réponses-régulateurs dont la protéine Rpa3018 sensible au potentiel redox. Cette étude a également révélé que, chez certaines souches de Rps. Palustris, la protéine RpBphP4 a perdu sa sensibilité à la lumière mais a acquis en contrepartie une sensibilité au potentiel redox tout en conservant sa capacité à réguler l'expression des antennes de type LH2 via un système à 2 composants. Dans un second temps, l'analyse de la séquence du génome de deux Bradyrhizobium photosynthétiques (ORS278 et BTAi1) a révélé que chaque souche possède un bactériophytochrome spécifique sûrement acquis par transfert horizontal. Les études menées sur ces différents bactériophytochromes ont mis en exergue la diversité de cette famille de senseurs de lumière ainsi que la complexité des voies de signalisation qu'ils initient
Rhodopseudomonas palustris is a photosynthetic purple bacteria which genome was completely sequenced. Six genes encoding putative bactériophytochromes are present in this genome. One of them plays an essential and unusual role in the synthesis of the photosystem. In this bacteria, three other bacteriophytochromes are localized near pucBA operons encoding polypeptides involved in the formation of light harvesting complexes associated with photosystem. First, this PhD work studied roles, properties and mechanisms of action of these three bacteriophytochromes. We showed that RpBphP2 and RpBphP3 act in tandem to regulate the expression of LH4 antennas. This signalling pathway use three reponse-regulators, one of them, Rpa3018 is rdox sensitive. In some strains of Rps. Palustris, a bactériophytochrome, RpBphP4, lost its light sensitivity and acquired a redox sensibility while keeping its ability to regulate the expression of these antennas. In a second time, analysis of the genome sequence of two photosynthetic Bradyrhizobium (ORS278 and BTAi1) revealed, in each strain, the presence of a specific bacteriophytochrome probably acquired by horizontal transfer. The properties of these various bacteriophytochromes led highlighted the variety of this family of light sensors as well as the complexity of the signalling pathways which they introduce

Abstract (sommario):
The recent surge in biodiesel production has resulted in a huge surplus of crude glycerol, a by-product of the process to the level of 10% by weight. This is turn has caused the price of glycerol to fall dramatically, and there are now few economically viable channels for using this resource: waste glycerol is usually combusted. Therefore, much interest has arisen in the possibility of making use of glycerol with biotechnology, as this would not only be a more efficient use of resources but also make biodiesel itself more commercially viable. The purple bacterium Rhodopseudomonas palustris is able to metabolize glycerol through photofermentation and thereby produce hydrogen, a commercially useful commodity. R. palustris is of particular interest for this purpose as, in contrast to many other species which have been investigated with a view to fermenting glycerol, it is highly tolerant of crude glycerol. The feedstock requires little purification or dilution to be made suitable for cultivation of R. palustris. Furthermore, the hydrogen gas produced by R. palustris when grown on glycerol is of high purity, and the organism's great metabolic diversity suggests it may be a useful strain for remediation of other waste materials. However, much groundwork is needed to establish R. palustris as a viable chassis organism for biotechnological purposes. This work sets out to establish optimal conditions for cultivating R. palustris in the laboratory, including the design of a suitable batch photobioreactor system. It also determines optimal conditions for electroporation of R. palustris for the purpose of knocking out endogenous genes or introducing heterologous genes. Furthermore, the introduction of heterologous genes is attempted in order to demonstrate the possibility of producing other high-value compounds with R. palustris, and several deletion strains with potential benefits for hydrogen production are created. Finally, several existing deletion strains are investigated to establish their suitability as chassis strains for further genetic manipulation.

Abstract (sommario):
2001/2002
This thesis mainly direct to a few transporter metalloproteins, in particular those containing metallo-organic prosthetic groups (the iron porphyrin and the cobalt corrin complexes ). The three-dimensional structures of the native cytochrome c2 from Rhodopseudomonas palustris and of its ammonia complex have been obtained at pH 4.4 and pH 8.5, respectively. The structure of the native form has been refined in the oxidised state at 1.70 À and in the reduced state at 1.95 À resolution. These are the first highresolution crystal structures in both oxidation states of a cytochrome c2 with relatively high redox potential (+365 mV). The differences between the two oxidation states of the native form, including the position of internal water molecules, are small. The positional change of a buried water molecule, located at the heme binding pocket near to the iron bonded Met, is the most prominent structural difference observed with the change of the iron oxidation state in the c-type cytochrome structures. In all oxidised forms this water molecule is found in a position different from that found in the reduced forms. On the contrary, in the oxidised form of the cytochrome c2 from Rhodopseudomonas palustris, this water molecule is detected in a position close to that found in the reduced form. The buried water molecule plays an important role in adjusting the midpoint redox potential of c-type cytochromes with alteration of the surrounding hydrogen bond network. The unusual six-residue insertion Gly82-Ala87, which precedes the heme binding Met93, forms an isolated 310-helix secondary structural element not previously observed in other c-type cytochromes. Furthermore, this cytochrome shows an extemal methionine residue involved in a strained folding near the exposed edge of the heme. The structural comparison of the present cytochrome c2 with other c-type cytochromes has revealed that the presence of such a residue, with torsion angles and 'V of about -140 and -130°, respectively, is a typical feature of this family of proteins. The refined crystal structure of the ammonia complex, obtained at 1.15 À resolution, shows that the sulphur atom of the Met93 axial ligand does not coordinate the heme iron-atom, but is replaced by an exogenous ammonia molecule. This is the only example so far reported of an X-ray structure with the heme iron coordinated by an ammonia molecule. The detachment of Met93 is accompanied by a very localised change in the backbone conformation, involving mainly the residues Lys92, Met93 and Thr94. Previous studies under typical denaturing conditions, including high pH values and the presence of exogenous ligands, have showed that the detachment of the Met axial ligand is a basic step in the folding/unfolding process of c-type cytochromes. The ammonia-adduct represents a structural model for this important step of the unfolding pathway. Factors proposed to be important for the methionine dissociation are the strength of the H-bond between the Met93 and Tyr66 residues that stabilises the nati ve form, and the presence, in this bacterial cytochrome c2 of the rare six-residue insertion in the helix 310 conformation that increases the Met loop flexibility. Transcobalamin is a cobalamin binding protein in mammalian plasma that facilitates the cellular uptake of vitamin B 12 • Whereas the X-ray structures of severa! B12-enzymes are available, no structural information on B12-transporting proteins has so far been reported. Human and bovine transcobalamin were expressed using ricombinant yeast cells and purified. Human transcobalamin was successfully crystallised usmg polyethylene glycol and ethanol as precipitants. Crystals belong to the orthorhombic space group P212121, with unit-cell parameters a= 49.04, b = 145.27, and e= 164.96 À. A complete data set to 3.2 À resolution was collected from a single crystal using s ynchrotron radiati on (Elettra, Trieste). Estimati on of the crystal packing (V m = 3.2 À 3 Da-1) and self-rotation function analysis suggest the presence of two molecules in the asymmetric unit related by a pseudo-twofold symmetry. Bovine transcobalamin was crystallised using polyethylene glycol and MPD. Crystals belong to the monoclinic space group P21 (a = 95.32, b = 100.19, e = 98.73 À and ~ = 96.9 À), and diffract to better then 2.0 À resolution. MAD data sets were collected at Elettra (Trieste) from a single crystal of the bovine protein, using the cobalamin Co atom as anomalous scatterer. Attempts to find the position of Co atoms in the monoclinic cell from Bijvoet difference Patterson maps are under way.

Abstract (sommario):
Studies of primary charge separation in photosynthetic reaction centres have largely been confined to the reaction centres of purple bacteria such as Rhodobacter sphaeroides and Rhodopseudomonas Viridis . Although reaction centres (RC's) from purple bacteria were first isolated 23 years ago, and despite the solution of their crystal structures, the precise mechanism of primary radical pair formation remains the subject of much contention.

Abstract (sommario):
The primary processes in photosynthesis occur in pigment-protein complex called reaction centers. The Chloroflexus aurantiacus (C. aurantiacus) reaction center is the smallest functionally active reaction center which has been isolated so far: it is composed of only two protein subunits, instead of four in Rhodopseudomonas viridis and three in Rhodobacter sphaeroides. As in the reaction centers of purple bacteria, the primary donor P is a dimer of bacteriochlorophyll (Bchl). In contrast, the different pigment composition (3 Bchl:3 Bphe) together with spectroscopic data (1,2), suggest that the accessory Bchl (BM)on the inactive M branch in reaction centers from purple bacteria, has been replaced by a bacteriopheophytin (Bphe) in C. aurantiacus reaction centers.
