Glycoside Hydrolase Family 91

Activities in Familyinulin lyase [DFA-I-forming] (EC; inulin lyase [DFA-III-forming] (EC; difructofuranose 1,2':2,3' dianhydride hydrolase [DFA-IIIase] (EC 3.2.1.-)
Mechanism Inverting
3D Structure Statusβ-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.
