Identification, characterization and molecular adaptation of class I redox systems for the production of hydroxylated diterpenoids.

<h4>Background</h4>De novo production of multi-hydroxylated diterpenoids is challenging due to the lack of efficient redox systems.<h4>Results</h4>In this study a new reductase/ferredoxin system from Streptomyces afghaniensis (AfR·Afx) was identified, which allowed the Escherichia coli-based production of the trihydroxylated diterpene cyclooctatin, a potent inhibitor of human lysophospholipase. This production system provides a 43-fold increase in cyclooctatin yield (15 mg/L) compared to the native producer. AfR·Afx is superior in activating the cylcooctatin-specific class I P450s CotB3/CotB4 compared to the conventional Pseudomonas putida derived PdR·Pdx model. To enhance the activity of the PdR·Pdx system, the molecular basis for these activity differences, was examined by molecular engineering.<h4>Conclusion</h4>We demonstrate that redox system engineering can boost and harmonize the catalytic efficiency of class I hydroxylase enzyme cascades. Enhancing CotB3/CotB4 activities also provided for identification of CotB3 substrate promiscuity and sinularcasbane D production, a functionalized diterpenoid originally isolated from the soft coral Sinularia sp. << Less

Cyclooctatin, a diterpene characterized by a 5-8-5 fused ring system, is a potent inhibitor of lysophospholipase. Here we report the cloning and characterization of a complete cyclooctatin biosynthetic gene cluster from Streptomyces melanosporofaciens MI614-43F2 and heterologous production of cyclooctatin in S. albus. Sequence analysis coupled with subcloning and gene deletion revealed that the minimal cyclooctatin biosynthetic gene cluster consists of four genes, cotB1 to cotB4, encoding geranylgeranyl diphosphate (GGDP) synthase, terpene cyclase (CotB2), and two cytochromes P450, respectively. Incubation of the recombinant CotB2 with GGDP resulted in the formation of cyclooctat-9-en-7-ol, an unprecedented tricyclic diterpene alcohol. The present study establishes the complete biosynthetic pathway of cyclooctatin and provides insights into both the stereospecific diterpene cyclization mechanism of the GGDP cyclase and the molecular bases for the stereospecific and regiospecific hydroxylation. << Less
