CC -!- FUNCTION: Involved in the biosynthesis of phenolic sesquiterpenes
CC natural products (Ref.2). Sesquiterpene synthase converting (2E,6E)-
CC farnesyl diphosphate (FPP) to alloaromadendrene and bicyclo-germacrene.
CC The product formation is dependent on the metal ions present and in
CC presence of manganese, bicyclo-germacrene is greatly favored while both
CC alloaromadendrene and bicyclo-germacrene are produced in equivalent
CC amounts in the presence of magnesium. Can also convert geranyl
CC diphosphate (GPP) to terpinolene, limonene and geraniol, and this
CC conversion is not affected by the presence of magnesium or manganese.
