(2E,6E)-farnesyl diphosphate ⇌ (+)-aristolochene + diphosphate
This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is (2E,6E)-farnesyl-diphosphate diphosphate-lyase (cyclizing, aristolochene-forming). Other names in common use include sesquiterpene cyclase, trans,trans-farnesyl diphosphate aristolochene-lyase, trans,trans-farnesyl-diphosphate diphosphate-lyase (cyclizing and aristolochene-forming). This enzyme participates in terpenoid biosynthesis.
This protein may use the morpheein model of allosteric regulation.[1]
