In enzymology a levan fructotransferase (DFA-IV-forming) (EC 4.2.2.16) is an enzyme that catalyzes the chemical reactionProduces di-beta-D-fructofuranose 26′:2’6-dianhydride (DFA IV) by successively eliminating the diminishing (2->6)-beta-D-fructan (levan) chain from the terminal D-fructosyl-D-fructosyl disaccharideThis enzyme belongs to the family of lyases specifically those carbon-oxygen lyases acting on polysaccharides.
