Accepted name: (-)-germacrene D synthase
Reaction: (2E,6E)-farnesyl diphosphate = (-)-germacrene D + diphosphate

Glossary: (-)-germacrene D = (1E,6E,8S)-1-methyl-5-methylidene-8-(propan-2-yl)cyclodeca-1,6-diene
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase [(-)-germacrene-D-forming]
Comments: In Solidago canadensis the biosynthesis results in the pro-R hydrogen at C-1 of the farnesy diphosphate ending up at C-11 of the (-)-germacrene D [1]. With Streptomyces coelicolor the pro-S hydrogen at C-1 ends up at C-11 of the (-)-germacrene D [2].
