A combined strategy for the overproduction of complex ergot alkaloid agroclavine.

ABSTRACT: Microbial cell factories (MCFs) and cell-free systems (CFSs) are generally considered as two unrelated approaches for the biosynthesis of biomolecules. In the current study, two systems were combined together for the overproduction of agroclavine (AC), a structurally complex ergot alkaloid. The whole biosynthetic pathway for AC was split into the early pathway and the late pathway at the point of the FAD-linked oxidoreductase EasE, which was reconstituted in an MCF (Aspergillus nidulans) and a four-enzyme CFS, respectively. The final titer of AC of this combined system is 1209 mg/L, which is the highest one that has been reported so far, to the best of our knowledge. The development of such a combined route could potentially avoid the limitations of both MCF and CFS systems, and boo
