Glossary: ()-exo-α-bergamotene = ()-trans-α-bergamotene = (1S,5S,6R)-2,6-dimethyl-6-(4-methylpent-3-en-1-yl)bicyclo[3.1.1]hept-2-ene
Systematic name: (2E,6E)-farnesyl-diphosphate lyase (cyclizing, ()-β-santalene-forming)
Comments: The enzyme synthesizes a mixture of sesquiterpenoids from (2E,6E)-farnesyl diphosphate. As well as ()-β-santalene (+)-α-santalene and ()-exo-α-bergamotene are formed with traces of (+)-epi-β-santalene. See EC 22.214.171.124 [(+)-α-santalene synthase], and EC 126.96.36.199 [()-exo-α-bergamotene synthase].
