The NADPH-Dependent thioredoxin reductase C-2-Cys peroxiredoxin redox system modulates the activity of thioredoxin x in arabidopsis chloroplasts [PDF]
The chloroplast redox network is composed of a complex set of thioredoxins (Trxs), reduced by ferredoxin (Fdx) via a Fdx-dependent Trx reductase (FTR), and an NADPH-dependent Trx reductase with a joint Trx domain, NTRC, which efficiently reduces 2-Cys ...

Effect of Ferredoxin on the Diaphorase Activity of Cyanobacterial Ferredoxin-NADP Reductase [PDF]
The interaction of ferredoxin-NADP reductase (FNR) and ferredoxin (Fd) results in an enhanced rate of reaction and a shift of the pH optimum for the FNR-mediated diaphorase reaction. Low concentrations of NaCl (

ABSTRACT Rhizorhabdus wittichii RW1 is known for its ability to degrade polycyclic aromatic hydrocarbons, such as dibenzo‐p‐dioxin (DD) and dibenzofuran (DF). We hypothesized that the R. wittichii RW1 benzoate 1,2‐dioxygenase shares electron transfer components with the DD/DF angular dioxygenase (DxnA1A2), similar to many aromatic hydrocarbon degrading

H2-Independent Growth of the Hydrogenotrophic Methanogen
Hydrogenotrophic methanogenic Archaea require reduced ferredoxin as an anaplerotic source of electrons for methanogenesis. H2 oxidation by the hydrogenase Eha provides these electrons, consistent with an H2 requirement for growth.

Abstract Purple sulfur bacteria (PSB) of the family Chromatiaceae (Gammaproteobacteria) can perform chemo‐ and photo‐lithoautotrophy (through anoxygenic photosynthesis) in anoxic layers of freshwater stratified (including meromictic) lakes. This group has been extensively studied via physiological and ecological approaches, albeit their genomics has ...

Using Label-Free Raman Spectroscopy Integrated with Microfluidic Chips to Probe Ferroptosis Networks in Cells [PDF]
Ferroptosis, a regulated form of cell death driven by oxidative stress and lipid peroxidation, has emerged as a pivotal research focus with implications across various cellular contexts. In this study, we employed a multifaceted approach, integrating label-free Raman spectroscopy and microfluidics to study the mechanisms underpinning ferroptosis.

Characterisation of components and mechanisms involved in redox-regulation of protein import into chloroplasts [PDF]
The vast majority of chloroplast proteins is encoded in the nucleus and thus has to be posttranslationally imported into the organelle, a process that is facilitated by two multimeric protein machineries, the Toc and Tic complexes (translocon at the ...

Ferrodoxin-dependent CO2 fixation in bean sprouts [PDF]
Extracts of bean sprouts are capable of reducing ferrodoxin and of catalyzing the incorporation of bicarbonate and acetyl coenzyme A into an organic compound that is likely to be pyruvate, in a reaction that requires reduced ferredoxin.

Impact of copper and iron on growth and silicic acid uptake in two Southern Ocean diatoms
Abstract Copper (Cu) and iron (Fe) are vital micronutrients that influence diatom physiology, growth rate, and nutrient stoichiometry. This study examines the interactive effects of Cu and Fe on two Southern Ocean diatoms, Proboscia inermis and Chaetoceros flexuosus, cultured under varying Fe and Cu conditions.

Unravelling the role of transient redox partner complexes in P450 electron transfer mechanics
The molecular evolution of cytochromes P450 and associated redox-driven oxidative catalysis remains a mystery in biology. It is widely believed that sterol 14α-demethylase (CYP51), an essential enzyme of sterol biosynthesis, is the ancestor of the whole ...
