Abstract

β-D-fructofuranosyl glycosidases are enzymes that produce health-beneficial fructooligosaccharides from natural fructans. In a recent issue of JBC, Kashima et al. identified a novel α-D-fructofuranosyl-active enzyme, αFFase1, from the caries-associated bacterium Bifidobacterium dentium. αFFase1 reversibly forms a potential prebiotic also found in caramel, difructose dianhydride I (DFA I), via intramolecular condensation of the substrate inulobiose. Kashima et al. elegantly combine NMR, X-ray crystallography, and molecular dynamics to describe an original mechanism for the reversible reactions catalyzed by αFFase1 that establishes the new glycoside hydrolase family GH172.
