Crystal structure of Aspergillus terreus aristolochene synthase complexed with farnesyl thiolodiphosphate (FSPP)

Template:ABSTRACT PUBMED 23905850

Function

[ARIS_ASPTE] Catalyzes the cyclization of trans,trans-farnesyl diphosphate (FPP) to the bicyclic sesquiterpene aristolochene. Produces germacrene A as an enzyme-bound intermediate that is not released by the enzyme, but is further cyclized to produce aristolochene. Aristolochene is the likely parent compound for a number of sesquiterpenoid toxins produced by filamentous fungi.^{[1] [2]}
