Terpentetriene synthase
Definition:
EC Tree > 4 Lyases > 4.2 Carbon-oxygen lyases > 4.2.3 Acting on phosphates > 4.2.3.36 terpentetriene synthase
Terpentetriene synthase requires Mg2+ for maximal activity but can use Mn2+, Fe2+ or Co2+ to a lesser extent. Following EC 5.5.1.15 (terpentedienyl-diphosphate synthase), it completes conversion of geranylgeranyl diphosphate into terpentetriene, a precursor of the diterpenoid antibiotic terpentecin; farnesyl diphosphate can also act as substrate. It cleaves terpentedienyl diphosphate into terpentetriene and diphosphate. Structurally it is a diterpene cyclase.
