Abstract
Polynucleotide phosphorylase is a highly conserved protein found in bacteria and fungi that can regulate the transcription of related enzymes involved in amino acid metabolism, organic acid metabolism, and cell biosynthesis. We studied the effect of polynucleotide phosphorylase on Saccharopolyspora pogona (S. pogona) growth and the synthesis of secondary metabolites. First, we generated the overexpression vector pOJ260-PermE-pnp via overlap extension PCR. The vector pOJ260-PermE-pnp was then introduced into S. pogona by conjugal transfer, thereby generating the recombination strain S. pogona-Pnp. Results showed that engineering strains possessed higher biomass than those of the wild-type strains. Moreover, the ability of these strains to produce spores on solid medium was stronger than that of the wild-type strains. HPLC results revealed that the butenyl-spinosyn yield in S. pogona-Pnp increased by 1.92-fold compared with that of S. pogona alone. These findings revealed that overexpression of polynucleotide phosphorylase effectively promoted butenyl-spinosyn biosynthesis in S. pogona. This result may be extended to other Streptomyces for strain improvement.
