title: Cytosolic, mitochondrial thioredoxins and thioredoxin reductases in Arabidopsis thaliana.
abstract: Thioredoxins, by reducing disulfide bridges are one of the main participants that regulate cellular redox balance. In plants, the thioredoxin system is particularly complex. The most well-known thioredoxins are the chloroplastic ones, that participate in the regulation of enzymatic activities during the transition between light and dark phases. The mitochondrial system composed of NADPH-dependent thioredoxin reductase and type o thioredoxin has only recently been described. The type h thioredoxin group is better known. Yeast complementation experiments demonstrated that Arabidopsis thaliana thioredoxins h have divergent functions, at least in Saccharomyces cerevisiae. They have diverse affinities for different target proteins, most probably because of structural differences. However, plant thioredoxin h functions still have to be defined.
