In enzymology, a methylenetetrahydromethanopterin dehydrogenase () is an enzyme that catalyzes the chemical reaction :5,10-methylenetetrahydromethanopterin + coenzyme F420 5,10-methenyltetrahydromethanopterin + reduced coenzyme F420 Thus, the two substrates of this enzyme are 5,10-methylenetetrahydromethanopterin and coenzyme F420, whereas its two products are 5,10-methenyltetrahydromethanopterin and reduced coenzyme F420. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors. The systematic name of this enzyme class is 5,10-methylenetetrahydromethanopterin:coenzyme-F420 oxidoreductase. Other names in common use include N5,N10-methylenetetrahydromethanopterin dehydrogenase, and 5,10-methylenetetrahydromethanopterin dehydrogenase. This enzyme participates in folate biosynthesis. ==Structural studies== As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes , , , and . 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「methylenetetrahydromethanopterin dehydrogenase」の詳細全文を読む スポンサード リンク
