Environment variations can modify plant metabolism in particular by production of reactive oxygen species (ROS) which are harmfull at high level. Enzymatic systems are to degrade these ROS but also repair oxidized molecules. They are composed by peroxidases (thioredoxins-reduced glutathione peroxidases and thioredoxin or glutaredoxin-reduced peroxiredoxins) using dithiol exchange for their activity. These systems present a complexity according to their multigenic family origin. Recombinant Prx-Grx hybrids have been produced giving clue to interactions between Prx and Grx. Enzymatic studies showed Prx IIF and IIE can reduced a wide range of substrates other than hydrogen peroxide, with variable activity. Furthermore they are not found identi...
