In enzymology, a levan fructotransferase (DFA-IV-forming) () is an enzyme that catalyzes the chemical reaction :Produces di-beta-D-fructofuranose 2,6':2',6-dianhydride (DFA IV) by successively eliminating the diminishing (2->6)-beta-D-fructan (levan) chain from the terminal D-fructosyl-D-fructosyl disaccharide This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on polysaccharides. The systematic name of this enzyme class is 2,6-beta-D-fructan lyase (di-beta-D-fructofuranose-2,6':2',6-dianhydride-forming). Other names in common use include 2,6-beta-D-fructan D-fructosyl-D-fructosyltransferase (forming, di-beta-D-fructofuranose 2,6':2',6-dianhydride), and levan fructotransferase. ==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「Levan fructotransferase (DFA-IV-forming)」の詳細全文を読む スポンサード リンク
