Hence, this enzyme has one substrate, trans,trans-farnesyl diphosphate, and two products, trichodiene and 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 trans,trans-farnesyl-diphosphate diphosphate-lyase (cyclizing, trichodiene-forming). Other names in common use include trichodiene synthetase, sesquiterpene cyclase, and trans,trans-farnesyl-diphosphate sesquiterpenoid-lyase. This enzyme participates in terpenoid biosynthesis.
Structural studies
As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes 1YJ4, 1YYQ, 1YYR, 1YYS, 1YYT, 1YYU, 2AEK, 2AEL, and 2AET.
