Regulation of alternative oxidase gene expression in soybean
Plant Molecular Biology, 2002Soybean (Glycine max cv. Stevens) suspension cells were used to investigate the expression of the alternative oxidase (Aox) multigene family. Suspension cells displayed very high rates of cyanide-insensitive respiration, but Aox3 was the only isoform detected in untreated cells. Incubation with antimycin A, citrate, salicylic acid or at low temperature

Alternative oxidase: a target and regulator of stress responses
Physiologia Plantarum, 2009The alternative oxidase (AOX) is found in all plants examined to date, fungi and lower invertebrates. We propose that AOX is not only part of the stress response in plants, but it also plays a central role in defining the stress response. Three lines of evidence support this proposal: (1) The absence of AOX leads to an alteration of stress defences in ...

The alternative oxidase is encoded in a multigene family in soybean
Planta, 1996The copy number of the alternative oxidase gene, Aox, was investigated in soybean (Glycine max L.) using a Polymerase chain reaction (PCR) approach to amplify fragments from soybean genomic DNA. The primers used were based on absolutely conserved regions of Aox cDNA clones from a variety of plant species and the yeast Hansenula anomala.

Trypanosome alternative oxidase: from molecule to function
Trends in Parasitology, 2006Trypanosome alternative oxidase (TAO) is the cytochrome-independent terminal oxidase of the mitochondrial electron transport chain. TAO is a diiron protein that transfers electrons from ubiquinol to oxygen, reducing the oxygen to water. The mammalian bloodstream forms of Trypanosoma brucei depend solely on TAO for respiration.

A structural model of the alternative oxidase of plant mitochondria
Biochemical Society Transactions, 1995The alternative oxidase branches from the main mitochondrial respiratory chain at the level of the ubiquinone pool, it i s non-protonmotive and an integral membrane protein with its active site located on the matrix side of the inner membrane [ I]. Activity of the alternative oxidase strongly correlates with the appearance of three proteins with Mr of ...

Alternative oxidase and plastoquinol terminal oxidase in marine prokaryotes of the Sargasso Sea
Gene, 2005Alternative oxidase (AOX) represents a non-energy conserving branch in mitochondrial electron transport while plastoquinol terminal oxidase (PTOX) represents a potential branch in photosynthetic electron transport. Using a metagenomics dataset, we have uncovered numerous and diverse AOX and PTOX genes from the Sargasso Sea. Sequence similarity, synteny

Structural insights into the alternative oxidases: are all oxidases made equal?
Biochemical Society Transactions, 2017The alternative oxidases (AOXs) are ubiquinol-oxidoreductases that are members of the diiron carboxylate superfamily. They are not only ubiquitously distributed within the plant kingdom but also found in increasing numbers within the fungal, protist, animal and prokaryotic kingdoms. Although functions of AOXs are highly diverse in general, they tend to

[Alternative oxidase in industrial fungi].
Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2015Filamentous fungi have been used in industrial fermentation extensively. Based on non-phosphorylating electron transport process, alternative respiration pathway (ARP) acts as an energy overflow, which can balance carbon metabolism and electron transport, allow the continuance of tricarboxylic acid cycle without the formation of ATP, and permit the ...

Functions of Alternative Terminal Oxidases
1978Functions of Alternative Terminal Oxidases is a collection of papers from the 11th meeting of the Federation of European Biochemical Societies in Copenhagen in 1977. The book opens with a review of the alternate electron transport mechanism to the main phosphorylating respiratory chain.
