Ketosteroid monooxygenase (, ''steroid-ketone monooxygenase'', ''progesterone, NADPH2:oxygen oxidoreductase (20-hydroxylating, ester-producing)'', ''17alpha-hydroxyprogesterone, NADPH2:oxygen oxidoreductase (20-hydroxylating, side-chain cleaving)'', ''androstenedione, NADPH2:oxygen oxidoreductase (17-hydroxylating, lactonizing)'') is an enzyme with system name ''ketosteroid,NADPH:oxygen oxidoreductase (20-hydroxylating, ester-producing/20-hydroxylating, side-chain cleaving/17-hydroxylating, lactonizing)''. This enzyme catalyses the following chemical reaction : ketosteroid + NADPH + H+ + O2 steroid ester/lactone + NADP+ + H2O (general reaction) :(1) progesterone + NADPH + H+ + O2 testosterone acetate + NADP+ + H2O :(2) androstenedione + NADPH + H+ + O2 testololactone + NADP+ + H2O :(3) 17alpha-hydroxyprogesterone + NADPH + H+ + O2 androstenedione + acetate + NADP+ + H2O Ketosteroid monooxygenase is a single FAD-containing enzyme that catalyses three types of monooxygenase reaction. == 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「Ketosteroid monooxygenase」の詳細全文を読む スポンサード リンク
