In enzymology, a 5-amino-6-(5-phosphoribosylamino)uracil reductase () is an enzyme that catalyzes the chemical reaction :5-amino-6-(5-phosphoribitylamino)uracil + NADP+ 5-amino-6-(5-phosphoribosylamino)uracil + NADPH + H+ Thus, the two substrates of this enzyme are 5-amino-6-(5-phosphoribitylamino)uracil and NADP+, whereas its 3 products are 5-amino-6-(5-phosphoribosylamino)uracil, NADPH, and H+. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 5-amino-6-(5-phosphoribitylamino)uracil:NADP+ 1'-oxidoreductase. This enzyme is also called aminodioxyphosphoribosylaminopyrimidine reductase. This enzyme participates in riboflavin metabolism. ==Structural studies== As of late 2007, 7 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「5-amino-6-(5-phosphoribosylamino)uracil reductase」の詳細全文を読む スポンサード リンク
