Immobilized uroporphyrinogen I synthetase from Rhodopseudomonas palustris
Biotechnology and Applied Biochemistry, 1990Rhodopseudomonas palustris uroporphyrinogen I synthetase (URO‐S) has been chemically attached to Sepharose 4B and some of its properties have been studied. When 7–8 mg protein/ml activated Sepharose was used, immobilized URO‐S retained 45% of the activity of the original soluble preparation, with a coupling yield of 66% after a period of 15 h.

Membrane Properties of Rhodopseudomonas palustris
1990Among purple bacteria, energy transformation rates are rather low in Rhodopseudomonas palustris (ATCC 11168) due to a weakly membrane-bound RpF1-ATPase. Cell breakage by high pressure or sonication treatment resulted in a crude chromatophore preparation with a lag phase of about 6 h where no energy induced H+ uptake or phosphorylation rate could be ...

[Thiosulfate metabolism in Rhodopseudomonas palustris].
Mikrobiologiia, 1980The cells of the purple nonsulfur bacterium Rhodopseudomonas palustris, Nakamura strain, are capable of oxidizing thiosulfate and sulfide both under the anaerobic conditions in the light and under the aerobic conditions in the dark. Regardless of the presence of thiosulfate in the medium, the cells contain thiosulfate reductase, rodanase, thiosulfate ...

Electricity Generation by Rhodopseudomonas palustris DX-1
Environmental Science & Technology, 2008Bacteria able to generate electricity in microbial fuel cells (MFCs) are of great interest, but there are few strains capable of high power production in these systems. Here we report that the phototrophic purple nonsulfur bacterium Rhodopseudomonas palustris DX-1, isolated from an MFC, produced electricity at higher power densities (2720 +/- 60 mW/m2)

The Photosynthetic Apparatus of Rhodopseudomonas palustris: Structures and Organization
Journal of Molecular Biology, 2006The structural analysis of the individual components of the photosynthetic apparatus of Rhodopseudomonas palustris, or those of related species, is almost complete. To shed light on the assembly and organization of this machinery, we have studied native membranes of Rps.palustris grown under different light conditions using atomic force microscopy (AFM)

Bacteriophytochromes Control Photosynthesis in Rhodopseudomonas palustris
2009The ability to endure and adapt to a broad array of environmental conditions is a feature of photosynthesizing organisms. This is particularly true of changing light conditions as acclimatization to light is of importance for energy utilization and for the prevention of radiation damage.

The adenylate kinases (EC 2.7.4.3) from photosynthetically grown Rhodopseudomonas palustris, Rhodopseudomonas sphaeroides and Rhodospirillum rubrum were purified to homogeneity by the same procedure. The purified enzymes showed optimal rates of activity with MgCl2 at 25° C and pH 8.0.

Phosphotransacetylase and Acetate Kinase from Rhodopseudomonas Palustris
1987Energy-linked NAD+ reduction and energy-dependent NADP+ transhydrogenat-ion in cell-free extracts from Rhodopseudomonas palustris are catalyzed by the supernatant fraction S-144 (1,2). Reduction of pyridine nucleotide is mediated by an ATP-driven reversal of electron transfer including cytochrome c oxidation and concomitantly occurring NAD+ reduction ...
