Other name(s): Cop4
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, cubebol-forming)
Comments: Requires Mg2+. The enzyme gives 28% cubebol, 29% ()-germacrene D, 10% (+)-δ-cadinene and traces of several other sesquiterpenoids. See also EC 220.127.116.11 ()-germacrene D synthase and EC 18.104.22.168 (+)-δ-cadinene synthase.
