ID 4.2.3.127 DE beta-copaene synthase. AN Cop4. CA (2E,6E)-farnesyl diphosphate = beta-copaene + diphosphate. CC -!- Isolated from the fungus Coprinus cinereus. CC -!- The enzyme also forms (+)-delta-cadinene, beta-cubebene, (+)-sativene CC and traces of several other sequiterpenoids. CC -!- beta-copaene is formed in the presence of Mg(2+) but not Mn(2+). CC -!- See EC 4.2.3.13 EC 4.2.3.128 and EC 4.2.3.129.
