| 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. |
