Isolated from the fungus?Coprinus cinereus. The enzyme also forms (+)-¦Ä-cadinene, ¦Â-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, (+)-¦Ä-cadinene synthase, EC?4.2.3.127, ¦Â-copaene synthase, EC?4.2.3.129, (+)-sativene synthase, and EC?4.2.3.23, germacrene A synthase.
