Abstract
Spinosad is a potent insecticide produced by Saccharopolyspora spinosa. However, it harbors certain limitations of a low growing rate and unfeasible genetic manipulation that can be overcome by adopting a superior platform, such as Streptomyces. Herein, we exploited the industrial tylosin-producing Streptomyces fradiae J1-021 for the heterologous production of spinosad. An engineered strain (HW01) with deletion of the tylosin biosynthetic gene cluster (BGC) was constructed and then transformed with the natural spinosad BGC. The distribution and expression levels of the tylosin BGC operons were assessed to construct a natural promoter library. The rate-limiting steps of spinosad biosynthesis were identified by analyzing the transcriptional expression of the spinosad biosynthetic genes. The stepwise engineering work involved the overexpression of the biosynthetic genes participating in rate-limiting pathways using strong promoters, affording an increase in spinosad production to 112.4 μg/L. These results demonstrate that strain HW01 has the potential to be used as a chassis for the heterologous production of polyketides.

Enhancing tylosin production by combinatorial overexpression of efflux, SAM biosynthesis, and regulatory genes in hyperproducing Streptomyces xinghaiensis strain.

Abstract
Tylosin is a 16-membered macrolide antibiotic widely used in veterinary medicine to control infections caused by Gram-positive pathogens and mycoplasmas. To improve the fermentation titer of tylosin in the hyperproducing Streptomyces xinghaiensis strain TL01, we sequenced its whole genome and identified the biosynthetic gene cluster therein. Overexpression of the tylosin efflux gene tlrC, the cluster-situated S-adenosyl methionine (SAM) synthetase gene metKcs, the SAM biosynthetic genes adoKcs-metFcs, or the pathway-specific activator gene tylR enhanced tylosin production by 18%, 12%, 11%, and 11% in the respective engineered strains TLPH08-2, TLPH09, TLPH10, and TLPH12. Co-overexpression of metKcs and adoKcs-metFcs as two transcripts increased tylosin production by 22% in the resultant strain TLPH11 compared to that in TL01. Furthermore, combinational overexpression of tlrC, metKcs, adoKcs-metFcs, and tylR as four transcripts increased tylosin production by 23% (10.93g/L) in the resultant strain TLPH17 compared to that in TL01. However, a negligible additive effect was displayed upon combinational overexpression in TLPH17 as suggested by the limited increment of fermentation titer compared to that in TLPH08-2. Transcription analyses indicated that the expression of tlrC and three SAM biosynthetic genes in TLPH17 was considerably lower than that of TLPH08-2 and TLPH11. Based on this observation, the five genes were rearranged into one or two operons to coordinate their overexpression, yielding two engineered strains TLPH23 and TLPH24, and leading to further enhancement of tylosin production over TLPH17. In particular, the production of TLPH23 reached 11.35 g/L. These findings indicated that the combinatorial strategy is a promising approach for enhancing tylosin production in high-yielding industrial strains.
