Accepted name: exo-α-bergamotene synthase
Reaction: (2E,6E)-farnesyl diphosphate = (-)-exo-α-bergamotene + 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
Other name(s): trans-α-bergamotene synthase; LaBERS (gene name)
Systematic name: (2E,6E)-farnesyl diphosphate lyase (cyclizing, (-)-exo-α-bergamotene-forming)
Comments: The enzyme synthesizes a mixture of sesquiterpenoids from (2E,6E)-farnesyl diphosphate. As well as (-)-exo-α-bergamotene (74%) there were (E)-nerolidol (10%), (Z)-α-bisabolene (6%), (E)-β-farnesene (5%) and β-sesquiphellandrene (1%).
