- Formiranje alfa-D-fruktofuranoza beta-D-fruktofuranoza 1,2':2,3'-dianhidrida (DFA III) putem sukcesivne eliminacije lanca (2->1)-beta-D-fruktana (inulina) sa terminalnog D-fruktozil-D-fruktozil disaharida.
Ovaj enzim, poput EC 4.2.2.16 i EC 4.2.2.17, eliminiše fruktanski lanac sa terminalnog disaharida formirajući difruktoza dianhidrid.
