Copalyl diphosphate synthases (CPSs) catalyze the crucial cyclization step in labdane diterpene biosynthesis to generate stereochemically distinct copalyl diphosphates (CPPs), however, the stereoselectivity within CPSs remains underexplored. Here, the authors report the 3D structure and oligomeric properties of syn-CPS from Oryza sativa, which originally produces syn-CPP but also ent-CPP after mutagenesis.
