Glycoside Hydrolase Family 91

Activities in FamilyDi-fructofuranose 1,2':2,3' dianhydride hydrolase (DFA IIIase) (EC 3.2.1.-);
Inulin fructotransferase (DFA-I-forming) (EC;
Inulin fructotransferase (DFA-III-forming) (EC;
Mechanism Inverting a
3D Structure Statusparallel β-helix
NoteWas temporarily changed into PL19 until it was recently realized that these "PLs" are analogous to GH23 SLTs/lysozymes (there is at least one hydrolase in the GH91 family) and therefore are better classified in the GH category. See CAZypedia (below) for more.
