BRITE hierarchy
Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, beta-cubebene-forming)
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate = beta-cubebene + diphosphate [RN:R10007]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448]
Product
beta-cubebene [CPD:C09648];
diphosphate [CPD:C00013]
Comment
Isolated from the fungus Coprinus cinereus. The enzyme also forms (+)-delta-cadinene, beta-copaene, (+)-sativene and traces of several other sequiterpenoids [2-4]. It is found in many higher plants such as Magnolia grandiflora (Southern Magnolia) together with germacrene A [1]. See EC 4.2.3.13, (+)-delta-cadinene synthase, EC 4.2.3.127, beta-copaene synthase, EC 4.2.3.129, (+)-sativene synthase, and EC 4.2.3.23, germacrene A synthase.
