Other name(s): OsKS5
Systematic name: ent-copalyl-diphosphate diphosphate-lyase [ent-pimara-8(14),15-diene-forming]
Comments: Unlike EC 4.2.3.29, ent-sandaracopimaradiene synthase, which can produce both ent-sandaracopimaradiene and ent-pimara-8(14),15-diene, this diterpene cyclase produces only ent-pimara-8(14),15-diene. ent-Pimara-8(14),15-diene is not a precursor in the biosynthesis of either gibberellins or phytoalexins.
