Lineage

Root
1. Class All alpha proteins [46456] (46456)
2. Fold Terpenoid synthases (48575)

multihelical; core: 8 helices (C-J) are arranged in 2 parallel layers

3. Superfamily Terpenoid synthases (48576)

duplication: two metal-binding sites are related by a pseudo dyad that also relates helices C-F to helices G-J
