Beta chamigrene synthase

Beta-chamigrene synthase (EC 4.2.3.78) is an enzyme with systematic name (2E,6E)-farnesyl diphosphate lyase (cyclizing, (+)-beta-chamigrene-forming). This enzyme catalyses the following chemical reaction

(2E,6E)-farnesyl diphosphate ⇌ (+)-beta-chamigrene + diphosphate

The recombinant enzyme from the plant Arabidopsis thaliana produces (+)-alpha-barbatene, (+)-thujopsene and (+)-beta-chamigrene.
