The enzyme synthesizes a mixture of sesquiterpenoids from (2E,6E)-farnesyl diphosphate. As well as (?)-¦Â-santalene (+)-¦Á-santalene and (?)-exo-¦Á-bergamotene are formed with traces of (+)-epi-¦Â-santalene. See EC?4.2.3.82?[(+)-¦Á-santalene synthase], and EC?4.2.3.81?[(?)-exo-¦Á-bergamotene synthase].
