Methods and approaches to study plant mitochondrial alternative oxidase.
The alternative oxidase is a non-proton motive 'alternative' to electron transport through the cytochrome pathway. Despite its wasteful nature in terms of energy conservation, the pathway is likely present throughout the plant kingdom and appears to be expressed in most plant tissues. A small alternative oxidase gene family exists, the members of which are differentially expressed in response t...

متن کاملSpecificity of the Organic Acid Activation of Alternative Oxidase in Plant Mitochondria.
The claim that succinate and malate can directly stimulate the activity of the alternative oxidase in plant mitochondria (A.M. Wagner, C.W.M. van den Bergen, H. Wincencjusz [1995] Plant Physiol 108: 1035-1042) was reinvestigated using sweet potato (Ipomoea batatas L.) mitochondria. In whole mitochondria, succinate (in the presence of malonate) and both L- and D-malate stimulated respiration via...
متن کاملReinstate hydrogen peroxide as the product of alternative oxidase of plant mitochondria.
Chill treatment of potato tubers for 8 days induced mitochondrial O2 consumption by cyanide-insensitive alternative oxidase (AOX). About half of the total O2 consumption in such mitochondria was found to be sensitive to salicylhydroxamate (SHAM), a known inhibitor of AOX activity. Addition of catalase to the reaction mixture of AOX during the reaction decreased the rate of SHAM-sensitive O2 con...
متن کاملFunctional expression of the plant alternative oxidase affects growth of the yeast Schizosaccharomyces pombe.
We have investigated the extent to which functional expression of the plant alternative oxidase (from Sauromatum guttatum) in Schizosaccharomyces pombe affects yeast growth. When cells are cultured on glycerol, the maximum specific growth rate is decreased from 0.13 to 0.11 h-1 while growth yield is lowered by 20% (from 1. 14 x 10(8) to 9.12 x 10(7) cells ml-1). Kinetic studies suggest that the...
