Accepted name: miltiradiene synthase

Reaction: (+)-copalyl diphosphate = miltiradiene + diphosphate

Other name(s): SmMDS; SmiKSL

Systematic name: (+)-copaly-diphosphate diphosphate-lyase (cyclizing, miltiradiene-forming)

Comments: Isolated from the plant Selaginella moellendorffii as a mutifunctional enzyme that also catalyses EC 5.5.1.12, copalyl diphosphate synthase [2]. In the plant Salvia miltiorrhiza the two enzymes are separate entities [1].
