Salvia miltiorrhiza Bunge (Danshen) is a medicinal plant of the Lamiaceae family, and its dried roots have long been used in traditional Chinese medicine with hydrophilic phenolic acids and tanshinones as pharmaceutically active components (Zhang et al., 2014; Xu et al., 2016). The first step of tanshinone biosynthesis is bicyclization of the general diterpene precursor (E,E,E)-geranylgeranyl diphosphate (GGPP) to copalyl diphosphate (CPP) by CPP synthases (CPSs), which is followed by a cyclization or rearrangement reaction catalyzed by kaurene synthase-like enzymes (KSL).
