DE   taxadiene synthase.
AN   taxa-4(5),11(12)-diene synthase.
AN   taxadiene cyclase.
CA   (2E,6E,10E)-geranylgeranyl diphosphate = diphosphate + taxa-4,11-diene.
CC   -!- This is the committed step in the biosynthesis of the diterpenoid
CC       antineoplastic drug Taxol (paclitaxel).
CC   -!- The cyclization involves a 1,5-hydride shift.
