1 Oxydo-reducteur systems and the thiol-dependent antioxidant equipment in Melampsora Benjamin Selles, Nicolas Rouhier, Eric Gelhaye

2 Oxygen is essential, but highly toxic Formation of reactive oxygen species (ROS) due to electron transport chains and oxidase functioning Release of ROS by plants as defense mechanism against pathogens Diffusion within cells : importance to have an antioxidant equipment in all sub-cellular compartments Oxydo-reducteur systems and the thiol- dependent antioxidant equipment in Melampsora

3 ROS formation

4 Superoxide and peroxide scavenging Catalases : haem peroxidase (peroxisomes) Thiol peroxidases : haem free thiol dependent peroxidases peroxiredoxins & glutathione peroxidases some specific glutathione-S-transferases Methionine sulfoxide reductases : indirect massive detoxification through MetSO reduction ROOH +ROH+ H2OH2O RSH 2 RS 2 + MetSO +Met+ H2OH2O RSH 2 RS 2 + H2O2H2O2 2H 2 O + O 2 H 2 O 2 + H 2 O 2 Superoxide dismutases 02.-02.- H 2 O 2 + 0 2 02.-02.- + 2 H + + 2 e -

9 Glutathione-S-transferases ► Complex and widespread superfamily ► Share thioredoxin fold ► Prominent roles :  phase II detoxication enzymes  Glutathione peroxidase  Nitrogen metabolism… ► Poorly characterized in fungi
