Abstract
Gougerotin is a peptidyl nucleoside antibiotic produced by Streptomyces graminearus. It is a specific inhibitor of protein synthesis and exhibits a broad spectrum of biological activities. Generation of an overproducing strain is crucial for the scale-up production of gougerotin. In this study, the natural and engineered gougerotin gene clusters were reassembled into an integrative plasmid by λ-red-mediated recombination technology combined with classic cloning methods. The resulting plasmids pGOU and pGOUe were introduced into S. graminearus to obtain recombinant strains Sgr-GOU and Sgr-GOUe, respectively. Compared with the wild-type strain, Sgr-GOU led to a maximum 1.3-fold increase in gougerotin production, while Sgr-GOUe resulted in a maximum 2.1-fold increase in gougerotin production. To further increase the yield of gougerotin, the effect of different precursors on its production was investigated. All precursors, including cytosine, serine, and glycine, had stimulatory effect on gougerotin production. The maximum gougerotin yield was achieved with Sgr-GOUe in the presence of glycine, and it was approximately 2.5-fold higher than that of the wild-type strain. The strategies used in this study can be extended to other Streptomyces for improving production of industrial important antibiotics.
