Non‐Respiratory Extracellular Electron Transfer Competes with Nitrogenase for Electrons in Rhodopseudomonas Palustris

open access: yesAdvanced Science, EarlyView.
This study develops a photosynthetic bioelectrochemical nitrogen fixation system for simultaneous nitrogen fixation and current generation using Rhodopseudomonas palustris. Notably, extracellular electron transfer (EET) serves as a redox balancing strategy, suppressing nitrogen fixation by competing with nitrogenase for electrons.

Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds

open access: yesAdvanced Science, EarlyView.
Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

Genomic Variation Underpins Genetic Divergence and Differing Salt Resilience in Sesbania bispinosa

open access: yesAdvanced Science, EarlyView.
Sesbania, a leguminous halophyte, thrives in saline soils. Comparative genomics reveals key genomic variations—particularly chromosomal inversions—are identified as contributors to population differentiation and salt resilience. These findings advance the understanding of genomic variation driving evolution and phenotypic differentiation and offer ...

Mechanical Stress Induced NOX2 Promotes Endothelial Dysfunction in Ventilator‐Induced Lung Injury: Potential Treatment with Quercetin

open access: yesAdvanced Science, EarlyView.
Abnormal mechanical stretch induced by mechanical ventilation (MV) disrupts endothelial junctions via the NOX2/ROS/CaMKII/ERK1/2 axis both in human aortic endothelial cells (HAECs) in vitro and in ventilator‐induced lung injury (VILI) in mice. Quercetin, an antioxidant predicted to bind to NOX2, can effectively prevent mechanical stretch‐induced ...

Macrophage‐Mediated Transport of Insoluble Indirubin Induces Hepatic Injury During Intestinal Inflammation

open access: yesAdvanced Science, EarlyView.
Plant‐derived bioactive molecules with low solubility and permeability induce hepatocyte injury, though the mechanisms driving their hepatic effects remain poorly understood. This study identifies a novel transport pathway in which poorly soluble indirubin accumulates in the liver via macrophage‐mediated uptake in Peyer's patches, exacerbating hepatic ...

To be or not to be a cytochrome: electrical characterizations are inconsistent with Geobacter cytochrome ‘nanowires’

open access: yesFrontiers in Microbiology
Geobacter sulfurreducens profoundly shapes Earth’s biogeochemistry by discharging respiratory electrons to minerals and other microbes through filaments of a two-decades-long debated identity. Cryogenic electron microscopy has revealed filaments of redox-

Could CuB be the site of redox linkage in cytochrome c oxidase? [PDF]

open access: yes, 1992
This paper explores the proton pumping function of cytochrome c oxidase [ferrocytochrome-c:oxygen oxidoreductase (EC 1.9.3.1)] based upon redox linkage at the "high-potential" CU(B) center.
