Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase (β-eudesmol-forming)
Comments: The recombinant enzyme from ginger (Zingiber zerumbet) gives 62.6% β-eudesmol, 16.8% 10-epi-γ-eudesmol (cf. EC 220.127.116.11, 10-epi-γ-eudesmol synthase), 10% α-eudesmol (cf. EC 18.104.22.168, α-eudesmol synthase), and 5.6% aristolene.
