Crystal Structure of Superoxide Reductase, 2ji1

Superoxide Reductase (SOR) catalyzes the conversion of reduced rubredoxin to rubredoxin using superoxide and H+. The catalysis reaction products are rubredoxin and H₂O₂. The images at the left and at the right correspond to one representative SOR, i.e. the crystal structure of Superoxide Reductase from Desulfovibrio baarsii (2ji1).
