Generation, Transfer, and Loss of Alternative Oxidase Paralogues in the Aspergillaceae Family [PDF]

Journal of Fungi, 2023
Alternative oxidase (Aox) is a terminal oxidase operating in branched electron transport. The activity correlates positively with overflow metabolisms in certain Aspergilli, converting intracellular glucose by the shortest possible path into organic ...

Localization and functional characterization of the alternative oxidase in Naegleria. [PDF]

J Eukaryot Microbiol, 2022
AbstractThe alternative oxidase (AOX) is a protein involved in supporting enzymatic reactions of the Krebs cycle in instances when the canonical (cytochrome‐mediated) respiratory chain has been inhibited, while allowing for the maintenance of cell growth and necessary metabolic processes for survival.

Alternative oxidase and plant stress tolerance [PDF]

Plant Signaling & Behavior, 2016
Alternative oxidase (AOX) is one of the terminal oxidases of the plant mitochondrial electron transport chain. AOX acts as a means to relax the highly coupled and tensed electron transport process in mitochondria thus providing and maintaining the much needed metabolic homeostasis by directly reducing oxygen to water.

The Human Gut Colonizer Blastocystis Respires Using Complex II and Alternative Oxidase to Buffer Transient Oxygen Fluctuations in the Gut

Frontiers in Cellular and Infection Microbiology, 2018
Blastocystis is the most common eukaryotic microbe in the human gut. It is linked to irritable bowel syndrome (IBS), but its role in disease has been contested considering its widespread nature. This organism is well-adapted to its anoxic niche and lacks

Roles for Plant Mitochondrial Alternative Oxidase Under Normoxia, Hypoxia, and Reoxygenation Conditions

Frontiers in Plant Science, 2020
Alternative oxidase (AOX) is a non-energy conserving terminal oxidase in the plant mitochondrial electron transport chain (ETC) that has a lower affinity for oxygen than does cytochrome (cyt) oxidase.

Alternative oxidase promotes high iron tolerance in Candida albicans [PDF]

Microbiology Spectrum, 2023
Although crucial for cellular functioning, iron is toxic when present in excess. Iron overload can create a labile iron pool (LIP) that harms the mitochondrion, resulting in disruption of oxidative respiration. Fungal pathogen C.

The Complementary Roles of Chloroplast Cyclic Electron Transport and Mitochondrial Alternative Oxidase to Ensure Photosynthetic Performance [PDF]

Frontiers in Plant Science, 2021
Chloroplasts use light energy and a linear electron transport (LET) pathway for the coupled generation of NADPH and ATP. It is widely accepted that the production ratio of ATP to NADPH is usually less than required to fulfill the energetic needs of the ...

Alternative oxidase in higher plants.

Acta Biochimica Polonica, 2003
Plant respiratory chain branches at the level of ubiquinone from where the electrons flow through the cytochrome pathway or to alternative oxidase. Transfer of electrons from ubiquinone to oxygen by alternative oxidase has a non-protonmotive character and, by bypassing two sites of H+ pumping in complexes III and IV, lowers the energy efficiency of ...

Alternative oxidase‐mediated respiration prevents lethal mitochondrial cardiomyopathy

EMBO Molecular Medicine, 2018
Alternative oxidase (AOX) is a non‐mammalian enzyme that can bypass blockade of the complex III‐IV segment of the respiratory chain (RC). We crossed a Ciona intestinalis AOX transgene into RC complex III (cIII)‐deficient Bcs1lp.S78G knock‐in mice ...

Structural and Biophysical Characterization of Purified Recombinant Arabidopsis thaliana's Alternative Oxidase 1A (rAtAOX1A): Interaction With Inhibitor(s) and Activator [PDF]

Frontiers in Plant Science, 2022
In higher plants, alternative oxidase (AOX) participates in a cyanide resistant and non-proton motive electron transport pathway of mitochondria, diverging from the ubiquinone pool. The physiological significance of AOX in biotic/abiotic stress tolerance
