The sequencing of the genome of Arabidopsis thaliana revealed that this plant contained numerous isoforms of thioredoxin (Trx), a protein involved in thiol-disulfide exchanges. On the basis of… (More)
We provide here an exhaustive overview of the glutathione (GSH) peroxidase (Gpx) family of poplar (Populus trichocarpa). Although these proteins were initially defined as GSH dependent, in fact they… (More)
Erv1 is a flavin-dependent sulfhydryl oxidase in the mitochondrial intermembrane space (IMS) that functions in the import of cysteine-rich proteins. Redox titrations of recombinant Erv1 showed that… (More)
Ferredoxin (Fd) is the major iron-containing protein in photosynthetic organisms and is central to reductive metabolism in the chloroplast. The Chlamydomonas reinhardtii genome encodes six plant type… (More)
Oxidation-reduction midpoint potentials were determined, as a function of pH, for the disulfide/dithiol couples of spinach and pea thioredoxins f, for spinach and Chlamydomonas reinhardtii… (More)
The plant plastidial thioredoxins (Trx) are involved in the light-dependent regulation of many enzymatic activities, owing to their thiol-disulfide interchange activity. Three different types of… (More)
Peroxiredoxins are ubiquitous thioredoxin- or glutaredoxin-dependent peroxidases, the function of which is to destroy peroxides. Peroxiredoxin Q, one of the four plant subtypes, is a homolog of the… (More)
All living organisms alter their physiology in response to changes in oxygen tension. The photosynthetic bacterium uses the RegB-RegA signal transduction cascade to control a wide variety of… (More)
Ammonium ion assimilation constitutes a central metabolic pathway in many organisms, and glutamate synthase, in concert with glutamine synthetase (GS, EC 6.3.1.2), plays the primary role of ammonium… (More)

Many species of purple photosynthetic bacteria repress synthesis of their photosystem in the presence of molecular oxygen. The bacterium Rhodobacter capsulatus mediates this process by repressing… (More)
