spinqualitylabelsall models Superoxide Reductase with Fe+3 ion (orange) complex with peroxide (red), Ca+2 ion (green) and nitrate (PDB entry 2ji3) Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Superoxide Reductase (SOR) catalyzes the conversion of reduced rubredoxin to rubredoxin using superoxide and H+. The catalysis reaction products are rubredoxin and H2O2. Structural highlights The active site of SOR contains Fe+3 ion and peroxide. Water molecules are shown as red spheres.
