Two bacterial diterpenesynthases from the actinomycete Allokutzneria albata were investigated, resulting in the identification of the structurally unprecedented compound spiroalbatene from the first and cembrene A from the second enzyme. Both enzymes were thoroughly investigated in terms of their mechanisms by isotope labeling experiments, site‐directed mutagenesis, and variation of the metal cofactors

geranylgeranyl diphosphate. In-depth mechanisticinvestigations using isotopicallylabelled precursors regarding the stereochemical course of both 1,11-cyclisation and 1,3-hydride shift furnished a detailed catalytic model suggesting the molecular basis of the observed low product selectivity. The enzyme's synthetic potential was also exploited in the preparation of sesquiterpene isotopomers, which provided
Digging up skeletons: We report the identification and the functional characterization of two terpene cyclases (DtcycA and DtcycB) that were mined from the genome of Streptomyces sp. SANK 60404. DtcycA and DtcycB are novel bacterialditerpenecyclases for the synthesis of the cembraneskeleton.
