Phytoene desaturase (zeta-carotene-forming) (, ''CrtIa'', ''2-step phytoene desaturase (ambiguous)'', ''two-step phytoene desaturase (ambiguous)'') is an enzyme with system name ''15-cis-phytoene:acceptor oxidoreductase (zeta-carotene-forming)''. This enzyme catalyses the following chemical reaction : 15-cis-phytoene + 2 acceptor all-trans-zeta-carotene + 2 reduced acceptor (overall reaction) : (1a) 15-cis-phytoene + acceptor all-trans-phytofluene + reduced acceptor : (1b) all-trans-phytofluene + acceptor all-trans-zeta-carotene + reduced acceptor The enzyme is involved in carotenoid biosynthesis. == 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「Phytoene desaturase (zeta-carotene-forming)」の詳細全文を読む スポンサード リンク
