Predicting compatibility between ferredoxins and the Fe protein of nitrogenase using in silico protein modeling. [PDF]
Protein SciAbstract Biological nitrogen fixation is the process by which certain bacteria and archaea use the enzyme nitrogenase to reduce atmospheric nitrogen into bioavailable ammonium. Engineering non‐nitrogen‐fixing organisms, like plants, to use nitrogenase could reduce dependency on synthetic fertilizer and mitigate the environmental impacts of industrial ...

Descriptions of Rhodopseudomonas parapalustris sp. nov., Rhodopseudomonas harwoodiae sp. nov. and Rhodopseudomonas pseudopalustris sp. nov., and emended description of Rhodopseudomonas palustris [PDF]
International Journal of Systematic and Evolutionary Microbiology, 2012 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.

Porin from Rhodopseudomonas sphaeroides [PDF]
Journal of Bacteriology, 1984 A protein homooligomer was purified from both the cell envelope fractions and the saline extracts of Rhodopseudomonas sphaeroides cells. This oligomer exhibited strong porin activity when reconstituted into proteoliposomes with egg phosphatidylcholine. In the saline extracts of both chemotrophically and phototrophically grown cells, the porin oligomer ...

Evolution of KaiC-Dependent Timekeepers: A Proto-circadian Timing Mechanism Confers Adaptive Fitness in the Purple Bacterium Rhodopseudomonas palustris. [PDF]
PLoS Genetics, 2016 Circadian (daily) rhythms are a fundamental and ubiquitous property of eukaryotic organisms. However, cyanobacteria are the only prokaryotic group for which bona fide circadian properties have been persuasively documented, even though homologs of the ...

Rhodopseudomonas palustris: A biotechnology chassis
Biotechnology Advances, 2022 Rhodopseudomonas palustris is an attractive option for biotechnical applications and industrial engineering due to its metabolic versatility and its ability to catabolize a wide variety of feedstocks and convert them to several high-value products. Given its adaptable metabolism, R.

n-Butanol production by Rhodopseudomonas palustris TIE-1
Communications Biology, 2021 Bai et al show that the anoxygenic phototroph strain TIE-1 can produce n-butanol using organic acids or CO2 as a carbon source, light as an energy source, and H2, Fe(II), or electrons from renewably generated electricity as an electron source. This study
