ID   5.5.1.15
DE   terpentedienyl-diphosphate synthase.
AN   clerodadienyl diphosphate synthase.
AN   terpentedienol diphosphate synthase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate = terpentedienyl diphosphate.
CC   -!- Contains a DXDD motif, which is a characteristic of diterpene cylases
CC       whose reactions are initiated by protonation at the 14,15-double bond
CC       of geranylgeranyl diphosphate (GGDP).
CC   -!- The triggering proton is lost at the end of the cyclization reaction.
CC   -!- The product of the reaction, terpentedienyl diphosphate, is the
CC       substrate for EC 4.2.3.36 and is a precursor of the diterpenoid
CC       antibiotic terpentecin.
