Known Activities	inulin lyase [DFA-I-forming] (EC 4.2.2.17); inulin lyase [DFA-III-forming] (EC 4.2.2.18); difructofuranose 1,2':2,3' dianhydride hydrolase [DFA-IIIase] (EC 3.2.1.-)
Mechanism	Inverting
3D Structure Status	b-helix
Note	Was 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.
