The oxygen‐sensing FixLJ represses nitrogen fixation in Rhodopseudomonas palustris in response to oxygen

open access: yesmLife, EarlyView.
Abstract Biological nitrogen fixation in symbiotic diazotrophs is subject to oxygen regulation by an oxygen‐sensing FixLJ two‐component system under micro‐oxic conditions. However, it remains unclear whether this mechanism is conserved in free‐living diazotrophs.

Engineering Fluoroacetate Dehalogenase by Growth‐Based Selections on Non‐Natural Organofluorides

open access: yesAngewandte Chemie, Volume 138, Issue 10, 2 March 2026.
We present a high‐throughput selection system to engineer fluoroacetate dehalogenases (FAcDs). By challenging E. coli populations that produce diverse FAcD libraries to grow on non‐natural organofluorides as their sole carbon source, we isolated a panel of FAcD variants with improved activity and altered substrate specificity.

Polyesterase activity and thermostability of carboxylesterases from Thermoleophilum album YS‐3

open access: yesThe FEBS Journal, EarlyView.
Three novel α/β‐hydrolases from thermophilic bacterium Thermoleophilum album display carboxylesterase and polyesterase activity. These enzymes hydrolyse PET, PLA and PCL both at high and moderate temperatures. TA21 shows superior activity, efficiently converting MHET to terephthalic acid. Structural features underlying substrate binding highlight their

Structural Homology of Reaction Centers from Rhodopseudomonas sphaeroides and Rhodopseudomonas viridis as Determined by X-ray Diffraction [PDF]

open access: yes, 1986
Crystals of the reaction center (RC) from Rhodopseudomonas sphaeroides with the space group P2_12_12_1, have been studied by x-ray diffraction. The Patterson search (molecular replacement) technique was used to analyze the data, with the structure of the

Multidimensional optimization for accelerating light-powered biocatalysis in Rhodopseudomonas palustris

open access: yesBiotechnology for Biofuels and Bioproducts, 2023
Background Whole-cell biocatalysis has been exploited to convert a variety of substrates into high-value bulk or chiral fine chemicals. However, the traditional whole-cell biocatalysis typically utilizes the heterotrophic microbes as the biocatalyst ...

Urologic Bacteriome: The Hero or the Villain in Prostate Cancer Onset, Progression, and Treatment?

open access: yesMedicinal Research Reviews, Volume 46, Issue 4, Page 1111-1151, July 2026.
ABSTRACT Prostate cancer (PCa) is the second most frequently diagnosed cancer in men worldwide and the fifth leading cause of cancer‐related mortality, presenting urgent unmet clinical needs in diagnosis and treatment. The recognition of the microbiome as a key factor in human health has prompted numerous studies, revealing an exciting new approach to ...

Photosynthetic primary production in the Mesoproterozoic

open access: yesNew Phytologist, Volume 251, Issue 1, Page 64-80, July 2026.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.
