ID 4.2.3.23 DE germacrene-A synthase. AN (+)-(10R)-germacrene A synthase. AN (+)-germacrene A synthase. AN GAS. AN germacrene A synthase. CA (2E,6E)-farnesyl diphosphate = (+)-(R)-germacrene A + diphosphate. CC -!- While germacrene A is an enzyme-bound intermediate in the CC biosynthesis of a number of phytoalexins, e.g. EC 4.2.3.9 from some CC species and EC 4.2.3.21, it is the sole sesquiterpenoid product CC formed in chicory.
