Background: Integrating vectors based on the int/attP loci of temperate phages are convenient and used widely,
particularly for cloning genes in Streptomyces spp.
Results: We have constructed and tested a novel integrating vector based on g27, encoding integrase, and attP
site from the phage, SV1. This plasmid, pBF3 integrates efficiently in S. coelicolor and S. lividans but surprisingly fails
to generate stable integrants in S. venezuelae, the natural host for phage SV1.
Conclusion: pBF3 promises to be a useful addition to the range of integrating vectors currently available for
Streptomyces molecular genetics.
