IntEnz Enzyme Nomenclature


Accepted name:
α-copaene synthase
Systematic name:
(2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, α-copaene-forming)



Isolated from Helianthus annuus (sunflower). The enzyme also produces β-caryophyllene, δ-cadinene and traces of other sesquiterpenoids. See EC (+)-δ-cadinene synthase, EC (−)-β-caryophyllene synthase.
