Glossary: τ-cadinol = 10β-cadin-4-en-10-ol

Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, τ-cadinol-forming)

Comments: Isolated from the plant Inula hupehensis. The enzyme also gives 10-epi-juneol and traces of other terpenoids, see EC, 10-epi-juneol synthase. It has also been isolated from the plants maize (Zea mays) and lavender (Lavandula angustifolia).
