Exo-alpha-bergamotene synthase

Exo-alpha-bergamotene synthase (EC 4.2.3.81, trans-alpha-bergamotene synthase, LaBERS (gene)) is an enzyme with systematic name (2E,6E)-farnesyl diphosphate lyase (cyclizing, (-)-exo-alpha-bergamotene-forming).^[1]^[2] This enzyme catalyses the following chemical reaction

(2E,6E)-farnesyl diphosphate

\rightleftharpoons

(-)-exo-alpha-bergamotene + diphosphate

The enzyme synthesizes a mixture of sesquiterpenoids from (2E,6E)-farnesyl diphosphate.
