(â)-Germacrene D synthase (EC 4.2.3.75) is an enzyme with systematic name (2E,6E)-farnesyl-diphosphate diphosphate-lyase ((â)-germacrene-D-forming). [1] [2] [3] [4] This enzyme catalyses the following chemical reaction
- (2E,6E)-farnesyl diphosphate (â)-germacrene D + diphosphate
In Solidago canadensis the biosynthesis results in the pro-R hydrogen at C-1 of the farnesyl diphosphate ending up at C-11 of the (â)-germacrene D .
