ENZYME entry: EC

Accepted Name
(+)-endo-beta-bergamotene synthase ((2Z,6Z)-farnesyl diphosphate cyclizing).
Reaction catalysed
(2Z,6Z)-farnesyl diphosphate <=> (+)-endo-beta-bergamotene
  • 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 (+)- alpha-santalene (see EC, while the (6S)-bisabolyl cation will give rise to (-)-endo-alpha-bergamotene (see EC, as well as (+)-endo-beta-bergamotene.
  • Small amounts of (-)-epi-beta-santalene are also formed from the (6R)-bisabolyl cation and small amounts of (-)-exo-alpha-bergamotene are formed from the (6S)-bisabolyl cation.
