Superoxide reductase is an enzyme that catalyzes the conversion of highly reactive and toxic superoxide (O2−) into less toxic hydrogen peroxide (H2O2): :reduced rubredoxin + O2− + 2 H+ rubredoxin + H2O2 :Fe2+ + O2− + 2 H+ Fe3++ H2O2 Hydrogen peroxide in turn is reduced to water by rubrerythrin. The 3 substrates of this enzyme are reduced rubredoxin, superoxide, and H+, whereas its two products are rubredoxin and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on superoxide as acceptor (only sub-subclass identified to date). The systematic name of this enzyme class is rubredoxin:superoxide oxidoreductase. Other names in common use include neelaredoxin, and desulfoferrodoxin. ==Structural studies== , 9 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Superoxide reductase」の詳細全文を読む スポンサード リンク
