Magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase (, ''Mg-protoporphyrin IX monomethyl ester (oxidative) cyclase'') is an enzyme with system name ''magnesium-protoporphyrin-IX 13-monomethyl ester,NADPH:oxygen oxidoreductase (hydroxylating) ''. This enzyme catalyses the following chemical reaction : magnesium-protoporphyrin IX 13-monomethyl ester + 3 NADPH + 3 H+ + 3 O2 divinylprotochlorophyllide + 3 NADP+ + 5 H2O (overall reaction) :(1a) magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + H+ + O2 131-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADP+ + H2O :(1b) 131-hydroxy-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + H+ + O2 131-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADP+ + 2 H2O :(1c) 131-oxo-magnesium-protoporphyrin IX 13-monomethyl ester + NADPH + H+ + O2 divinylprotochlorophyllide + NADP+ + 2 H2O This enzyme requires Fe(II) for activity. == 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「Magnesium-protoporphyrin IX monomethyl ester (oxidative) cyclase」の詳細全文を読む スポンサード リンク
