Streptomyces host. The generation of labda-8(17),12(E),14-triene (1) by CldB and CldD was reconfirmed by enzymatic synthesis. Furthermore, labda-8(17),13(16),14-triene (2) was generated by SCLAV_p0491 and CldB, and ladba-7,12(E),14-triene (3) by CldD and SCLAV_p0490. SCLAV_p0491 and SCLAV_p0490 catalyzed the generation of the novel diterpene hydrocarbon, labda-7,13(16),14-triene (4).

The biogenesis of tetracarbocyclic diterpenes is considered to involve cyclisation via a bicyclic C-13 carbonium ion. This species has been generated in vitro from manool and Δ13-manool and found to give, in refluxing acetic acid, a 1:1 mixture of Δ13-manool acetate and olefins. The latter consisted mainly of labdatrienes with smaller amounts of three classes of cyclized products. Ring closure between
