Accepted name: difructose-anhydride synthase
Reaction: bis-D-fructose 2′,1:2,1′-dianhydride + H2O = inulobiose
Other name(s): inulobiose hydrolase
Systematic name: bis-D-fructose 2′,1:2,1′-dianhydride fructohydrolase
Comments: Produces difructose anhydride by the reverse reaction of partial hydrolysis, forming an α-fructosidic linkage.
