Enzymic formation of di-D-fructose 1,2'; 2,1' dianhydride from inulobiose by Aspergillus fumigatus.
The enzyme of Aspergillus fumigatus which produces di-D-fructose 1,2'; 2,1' dianhydride (difructose anhydride I) (Tanaka et al., 1979) was investigated for its mode of action. Fractionation and purification of the enzyme showed that it produced difructose anhydride I not from inulin but from inulobiose by the reverse reaction of the partial hydrolysis of difructose anhydride I.
