α-Eudesmol synthase (EC 4.2.3.85) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase (α-eudesmol-forming). It catalyses the following chemical reaction
(2E,6E)-farnesyl diphosphate + H2O α-eudesmol + diphosphate
The recombinant enzyme from ginger (Zingiber zerumbet) gives β-eudesmol, 10-epi-γ-eudesmol, α-eudesmol and aristolene.
