In enzymology, a cyanocobalamin reductase (cyanide-eliminating) () is an enzyme that catalyzes the chemical reaction :cob(I)alamin + cyanide + NADP+ cyanocob(III)alamin + NADPH + H+ The 3 substrates of this enzyme are cob(I)alamin, cyanide, and NADP+, whereas its 3 products are cyanocob(III)alamin, NADPH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those that oxidize metal ions and use NAD+ or NADP+ as an electron acceptor (for that oxidization reaction). The systematic name of this enzyme class is cob(I)alamin, cyanide:NADP+ oxidoreductase. Other names in common use include cyanocobalamin reductase, cyanocobalamin reductase (NADPH, cyanide-eliminating), cyanocobalamin reductase (NADPH, CN-eliminating), and NADPH:cyanocob(III)alamin oxidoreductase (cyanide-eliminating). This enzyme participates in porphyrin and chlorophyll metabolism. It uses one cofactor, FAD. ==References== * 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「Cyanocobalamin reductase (cyanide-eliminating)」の詳細全文を読む スポンサード リンク
