EC 4.2.3.84     
Accepted name: 10-epi-γ-eudesmol synthase
Reaction: (2E,6E)-farnesyl diphosphate + H2O = 10-epi-γ-eudesmol + diphosphate

Glossary: 10-epi-γ-eudesmol = 2-[(2R,4aS)-4a,8-dimethyl-1,2,3,4,4a,5,6,7-octahydronaphthalen-2-yl]propan-2-ol
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (10-epi-γ-eudesmol-forming)
Comments: The recombinant enzyme from ginger (Zingiber zerumbet) gives 62.6% β-eudesmol, 16.8% 10-epi-γ-eudesmol, 10% α-eudesmol, and 5.6% aristolene. cf. EC 4.2.3.68 (β-eudesmol synthase) and EC 4.2.3.85 (α-eudesmol synthase)
