Protein: Ent-kaurene synthase 1, chloroplastic (IeKS1) (EC 4.2.3.19) (A0A3G1QTS7)
Organism: Isodon eriocalyx (Plectranthus eriocalyx)
Function: Involved in the biosynthesis of ent-kaurene diterpenoids natural products such as oridonin, miltiradiene, eriocalyxin B and nezukol, known to exhibit antitumor, anti-inflammatory and antibacterial activities, and in the production of gibberellins phytohormones. Catalyzes the conversion of ent-copalyl diphosphate (ent-CPP) to ent-kaurene.
Subcellular location: Plastid, chloroplast {ECO:0000255}.
