Sysname
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, alpha-copaene-forming)
Reaction(IUBMB)
(2E,6E)-farnesyl diphosphate = (-)-alpha-copaene + diphosphate [RN:R10584]
Reaction(KEGG)
Substrate
(2E,6E)-farnesyl diphosphate [CPD:C00448]
Product
(-)-alpha-copaene [CPD:C09639];
diphosphate [CPD:C00013]
Comment
Isolated from Helianthus annuus (sunflower). The enzyme also produces beta-caryophyllene, delta-cadinene and traces of other sesquiterpenoids. See EC 4.2.3.13 (+)-delta-cadinene synthase, EC 4.2.3.57 (-)-beta-caryophyllene synthase.
