In enzymology, a cob(II)alamin reductase () is an enzyme that catalyzes the chemical reaction :2 cob(I)alamin + NAD+ 2 cob(II)alamin + NADH + H+ Thus, the two substrates of this enzyme are cob(I)alamin and NAD+, whereas its 3 products are cob(II)alamin, NADH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those oxidizing metal ion with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is cob(I)alamin:NAD+ oxidoreductase. Other names in common use include vitamin B12r reductase, B12r reductase, and NADH2:cob(II)alamin oxidoreductase. This enzyme participates in porphyrin and chlorophyll metabolism. It employs 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「Cob(II)alamin reductase」の詳細全文を読む スポンサード リンク
