In enzymology an inulin fructotransferase (DFA-I-forming) (EC 4.2.2.17) is an enzyme that catalyzes the chemical reactionProduces alpha-D-fructofuranose beta-D-fructofuranose 12′:21′-dianhydride (DFA I) by successively eliminating the diminishing (2->1)-beta-D-fructan (inulin) 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.
