In enzymology, a thymine dioxygenase () is an enzyme that catalyzes the chemical reaction :thymine + 2-oxoglutarate + O2 5-hydroxymethyluracil + succinate + CO2 The 3 substrates of this enzyme are thymine, 2-oxoglutarate, and O2, whereas its 3 products are 5-hydroxymethyluracil, succinate, and CO2. This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is thymine,2-oxoglutarate:oxygen oxidoreductase (7-hydroxylating). Other names in common use include thymine 7-hydroxylase, 5-hydroxy-methyluracil dioxygenase, and 5-hydroxymethyluracil oxygenase. It has 2 cofactors: iron, and Ascorbate. ==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「Thymine dioxygenase」の詳細全文を読む スポンサード リンク
