Function
Involved in the biosynthesis of the bicyclic sesquiterpene (S)-beta-macrocarpene. Can use both geranyl diphosphate and farnesyl diphosphate as substrate, but not geranylgeranyl diphosphate. Produces mainly (S)-beta-macrocarpene, but also smaller amounts of beta-bisabolene and (E)-beta-farnesene when used with farnesyl diphosphate as substrate. In the presence of geranyl diphosphate, produces the acyclic monoterpenes beta-myrcene and linalool along with minor amounts of the cyclic compounds limonene, alpha-thujene, sabinene and alpha-terpinolene. May be involved in plant defense.
