Figure 1: Reactions catalyzed by superoxide dismutase (SOD), catalase, and glutathione peroxidases. Superoxide dismutases (SOD) convert to O2 and H2O2. Catalase and glutathione peroxidases convert H2O2 to water. Protein structures represented in this figure are available in the Protein Data Bank (PDB; http://www.rcsb.org/pdb/home/home.do). PDB ID, are referred in brackets.
