Systematic name: (2E,6E)-farnesyl diphosphate lyase (cyclizing, (+)-β-chamigrene-forming)
Comments: The recombinant enzyme from the plant Arabidopsis thaliana produces 27.3% (+)-α-barbatene, 17.8% (+)-thujopsene and 9.9% (+)-β-chamigrene [1] plus traces of other sesquiterpenoids [2]. See EC 4.2.3.69 (+)-α-barbatene synthase, and EC 4.2.3.79 thujopsene synthase.
