In enzymology, a L-gulonate 3-dehydrogenase () is an enzyme that catalyzes the chemical reaction :L-gulonate + NAD+ 3-dehydro-L-gulonate + NADH + H+ Thus, the two substrates of this enzyme are L-gulonate and NAD+, whereas its 3 products are 3-dehydro-L-gulonate, NADH, 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 L-gulonate:NAD+ 3-oxidoreductase. Other names in common use include L-3-aldonate dehydrogenase, L-3-aldonic dehydrogenase, L-gulonic acid dehydrogenase, L-beta-hydroxyacid dehydrogenase, L-beta-hydroxy-acid-NAD+-oxidoreductase, and L-3-hydroxyacid dehydrogenase. This enzyme participates in pentose and glucuronate interconversions. ==Structural studies== As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code . 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「L-gulonate 3-dehydrogenase」の詳細全文を読む スポンサード リンク
