ABSTRACT: Rhodopseudomonas palustris strain SA008.1.07 can use syringic acid as sole organic carbon source anaerobically. Grew all anaerobically in various carbon sources: syringic acid, succinate, and p-hydroxybenzoic acid.

Identification of a previously uncharacterised polypeptide component of the Rhodopseudomonas palustris light-harvesting 2 complex.

Project description:The purple bacterium Rhodopseudomonas palustris is a model organism for dissecting the energy and electron transfer processes that have evolved in phototrophic organisms. This bacterium is of particular interest because, in addition to driving its metabolism via solar energy capture, it is capable of nitrogen and carbon dioxide fixation, producing hydrogen and utilising a wide range of organic compounds. Understanding these processes underpins the potential exploitation of Rhodopseudomonas palustris for synthetic biology, biohydrogen production and bioremediation, for example. Like other purple bacteria, Rhodopseudomonas palustris has 2 light-harvesting (LH) systems: LH1 and LH2. The former has already been extensively characterised by X-ray crystallography and cryo-EM. The aim of this proteomics project is to provide complementary information to support the cryo-EM mapping of LH2 structure.

Gene expression patterns of a Rhodopseudomonas palustris ΔregSR strain under photoheterotrophic growth conditions

Project description:The redox-sensing two-component signal transduction system, RegSR, in Rhodopseudomonas palustris has been shown to regulate an uptake hydrogenase in response to varying cellular redox states; however, its role is still largely undefined. Here, we used RNA sequencing to compare gene expression patterns in wild type R. palustris strain CGA010 to a ΔregSR derivative, CGA2023, under varying metabolic conditions. Growth conditions were chosen to utilize the different metabolic capabilites of R. palustris and, thus, present a variety of different redox challenges to the cell.

FixK, a universal regulator of microaerobic growth, controls photosynthesis in Rhodopseudomonas palustris

Project description:Facultative phototrophic bacteria are excellent models for analyzing the coordination of major metabolic traits including oxidative phosphorylation, photophosphorylation, carbon dioxide fixation and nitrogen fixation. In Rhodobacter sphaeroides and R. capsulatus, a two-component system called RegBA (PrrBA) controls these functions and it has been thought that this redox sensing regulatory system was essential for coordinating electron flow and could not be easily replaced in facultative phototrophs. Here we show that this is not the case and that the oxygen-sensing FixlJ-K system, initially described in rhizobia, controls microaerobic respiration, photophosphorylation and several other metabolic traits in Rhodopseudomonas palustris. A R. palustris fixK mutant grew normally aerobically but was impaired in microaerobic growth. It was also severely impaired in photosynthetic growth and has very little bacteriochlorophyll. Transcriptome analyses indicated that FixK positively regulates heme and bacteriochlorophyll biosynthesis, cbb3 oxidase and NADH dehydrogenase genes, as well as genes for hydrogen uptake, iron oxidation, and aromatic compound degradation. Electrophoretic mobility shift assays showed that FixK binds directly to the promoters of a bacteriochlorophyll biosynthesis operon, a bacteriophytochrome-histidine kinase gene and the fnr-type regulatory gene, aadR. AadR is likely responsible for mediating some indirect effects of FixK on expression of anaerobic genes. These results underscore that physiologically similar bacteria can use very different regulatory strategies to control common major metabolisms. Comparison of transcription profiles of Rhodopseudomonas palustris wild type and fixK mutant grown microaerobically.
