Description
Requires Mg2+ for maximal activity but can use Mn2+, Fe2+ or Co2+ to a lesser extent. Following on from EC 5.5.1.15, terpentedienyl-diphosphate synthase, this enzyme completes the transformation of geranylgeranyl diphosphate (GGDP) into terpentetriene, which is a precursor of the diterpenoid antibiotic terpentecin. Farnesyl diphosphate can also act as a substrate
