Integrative vector is for general use in Streptomyces. For example, producing marked strains for re-isolation experiments, or gene expression, over expression, or complementation. This vector can be replicated within Escherichia coli for cloning, upon transformation into Streptomyces via Tri-parental mating this vector will integrate into the genome at the ΦBT1 attB site.


  • Kanamycin resistance gene
  • ΦBT1 attB phage integration site and integrase
  • Multiple cloning site
  • Origin of conjugative transfer (oriT)
  • Origin of replication for E. coli (pBR322oriF)


Backbone vector pSET152 was modified to replace the ΦC31 integrative machinery with the ΦBT1 integrative machinery by Maggie Smiths group, published in 20031.
