||The enzyme synthesizes a mixture of sesquiterpenoids from (2Z,6Z)-farnesyl diphosphate. Following dephosphorylation of (2Z,6Z)-farnesyl diphosphate, the (2Z,6Z)-farnesyl carbocation is converted to either the (6R)- or the (6S)-bisabolyl cations depending on the stereochemistry of the 6,1 closure. The (6R)-bisabolyl cation will then lead to the formation of (+)-α-santalene (EC 22.214.171.124), while the (6S)-bisabolyl cation will give rise to (+)-endo-β-bergamotene (see EC 126.96.36.199) as well as (-)-endo-α-bergamotene (see EC 188.8.131.52). Small amounts of (-)-epi-β-santalene are also formed from the (6R)-bisabolyl cation and small amounts of (-)-exo-α-bergamotene are formed from the (6S)-bisabolyl cation .
