Description: Product divergence of terpene synthase at non-optimal environments such as high temperature is largely dependent on protein local residues around active site than residue-independent transition of substrate intermediate.

== Function ==
[[Category: O'Maille, P.E]]
[https://www.uniprot.org/uniprot/5EAS_TOBAC 5EAS_TOBAC] Catalyzes the cyclization of trans,trans-farnesyl diphosphate (FPP) to the bicyclic intermediate 5-epi-aristolochene, initial step in the conversion of FPP to the sesquiterpenoid antifungal phytoalexin capsidiol. Produces germacrene A as an enzyme-bound intermediate that is not released by the enzyme, but is further cyclized to produce the bicyclic 5-epi-aristolochene.
