DE   levopimaradiene synthase.
CA   (+)-copalyl diphosphate = abieta-8(14),12-diene + diphosphate.
CC   -!- In Ginkgo, the enzyme catalyzes the initial cyclization step in the
CC       biosynthesis of ginkgolides, a structurally unique family of
CC       diterpenoids that are highly specific platelet-activating-factor
CC       receptor antagonists.
CC   -!- Levopimaradiene is widely distributed in higher plants.
CC   -!- In some species the enzyme also forms abietadiene, palustradiene,
CC       and neoabietadiene.
