Protein

Aristolochene synthase

Gene

ARI1

Organism
Penicillium roqueforti
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

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.2 Publications

Catalytic activityi

(2E,6E)-farnesyl diphosphate = aristolochene + diphosphate.1 Publication
