EC 4.2.3.82     
Accepted name: α-santalene synthase
Reaction: (2E,6E)-farnesyl diphosphate = (+)-α-santalene + diphosphate

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, (+)-α-santalene-forming)
Comments: The enzyme synthesizes a mixture of sesquiterpenoids from (2E,6E)-farnesyl diphosphate. As well as (+)-α-santalene, (-)-β-santalene and (-)-exo-α-bergamotene are formed with traces of (+)-epi-β-santalene. See EC 4.2.3.83 [(-)-β-santalene synthase], and EC 4.2.3.81 [(-)-exo-α-bergamotene synthase]. cf. EC 4.2.3.50 α-santalene synthase [(2Z,6Z)-farnesyl diphosphate cyclizing]
