Glossary: (+)-germacrene D = (1E,6E,8R)-1-methyl-5-methylidene-8-(propan-2-yl)cyclodeca-1,6-diene
Systematic name: (2E,6E)-farnesyl-diphosphate diphosphate-lyase [(+)-germacrene-D-forming]
Comments: Requires Mg2+, Mn2+, Ni2+ or Co2+. The formation of (+)-germacrene D involves a 1,2-hydride shift whereas for (–)-germacrene D there is a 1,3-hydride shift (see EC 4.2.3.75).
