In enzymology, a dihydroxy-acid dehydratase () is an enzyme that catalyzes the chemical reaction :2,3-dihydroxy-3-methylbutanoate 3-methyl-2-oxobutanoate + H2O Hence, this enzyme has one substrate, 2,3-dihydroxy-3-methylbutanoate, and two products, 3-methyl-2-oxobutanoate (α-ketoisovaleric acid) and H2O. This enzyme participates in valine, leucine and isoleucine biosynthesis and pantothenate and coenzyme A (CoA) biosynthesis. == Nomenclature == This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is 2,3-dihydroxy-3-methylbutanoate hydro-lyase (3-methyl-2-oxobutanoate-forming). Other names in common use include * acetohydroxyacid dehydratase, * alpha,beta-dihydroxyacid dehydratase, * 2,3-dihydroxyisovalerate dehydratase, * alpha,beta-dihydroxyisovalerate dehydratase, * dihydroxy acid dehydrase, * DHAD, * and 2,3-dihydroxy-acid hydro-lyase. 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「Dihydroxy-acid dehydratase」の詳細全文を読む スポンサード リンク
