| Systematic name: |
(2E,6E)-farnesyl-diphosphate diphosphate-lyase [(+)-α-barbatene-forming] |
| Comments: |
The recombinant enzyme from the plant Arabidopsis thaliana produces 27.3% α-barbatene, 17.8% thujopsene (cf. EC 4.2.3.79, thujopsene synthase) and 9.9% β-chamigrene (cf. EC 4.2.3.78, β-chamigrene synthase) [1] plus traces of other sesquiterpenoids [2]. |
