Other name(s): SmMDS; SmiKSL; RoKSL
Systematic name: (+)-copalyl-diphosphate diphosphate-lyase (cyclizing, miltiradiene-forming)
Comments: Isolated from the plants Rosmarinus officinalis (rosemary) and Salvia miltiorrhiza. The enzyme from the plant Selaginella moellendorffii is mutifunctional and also catalyses EC 5.5.1.12, copalyl diphosphate synthase [2].
