Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Modified alternative oxidase expression results in different reactive oxygen species content in Arabidopsis cell culture but not in whole plants

, 2012
Alternative oxidase (AOX) transfers electrons from ubiquinone to oxygen in the respiratory chain of plant mitochondria. It is widely accepted that AOX functions as a mechanism decreasing the formation of reactive oxygen species (ROS) produced during ...

Downregulation of mitochondrial alternative oxidase affects chloroplast function, redox status and stress response in a marine diatom.

New Phytologist, 2018
Diatom dominance in contemporary aquatic environments indicates that they have developed unique and effective mechanisms to cope with the rapid and considerable fluctuations that characterize these environments. In view of their evolutionary history from

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

FEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Alternative oxidase: a defence against metabolic fluctuations?

, 2009
An increasing number of oscillating or fluctuating cellular systems have been recently described following the adaptation of fluorescent technology. In diverse organisms, these variously involve signalling factors, heat production, central metabolism and

AOX Affects the Synthesis of Polysaccharides by Regulating the Reactive Oxygen Species in Ganoderma lucidum

Foods
Alternative oxidase (AOX) is a terminal oxidase in the mitochondrial electron transport chain that does not contribute to the generation of ATP. It plays a critical role in maintaining the balance between reactive oxygen species (ROS) production and ...

The D-channel of cytochrome oxidase: An alternative view

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2011
The D-pathway in A-type cytochrome c oxidases conducts protons from a conserved aspartate on the negatively charged N-side of the membrane to a conserved glutamic acid at about the middle of the membrane dielectric. Extensive work in the past has indicated that all four protons pumped across the membrane on reduction of O(2) to water are transferred ...

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

Engineering the substrate specificity of galactose oxidase [PDF]

, 2013
Biocatalysis, the use of enzymes to catalyse the generation of specific chemicals, has a number of advantages including high specificity, lower energy requirements and greater sustainability over an equivalent chemical process.
