Abstract: The genetics of streptomycin production is well characterized in Streptomyces griseus. More than 25 clustered genes encode proteins involved in biosynthesis, regulation and transport functions. StrR, the pathway specific transcriptional activator or regulator that located in this cluster, then induces transcription of other streptomycin production genes by binding multiple sites in the gene cluster. We aim to put strR gene in to different multicopy and integrated expression vector specifically designed for Streptomyces. To start with, the isolated strR gene was ligated into pBluescript (pBs) vector and transformed into different strains of Escherichia coli. The correct structure of the recombinant plasmid, isolated from transformed E. coli, was confirmed using gel electrophoresis, PCR and double digested with restriction enzymes BamHI and EcoRI. Finally the plasmid map, named pFDstrR. This unique vector has a much expanded Multiple Cloning Site (MCS), which makes it suitable for different purposes of gene cloning and also site directed mutagenesis or gene targeting. This gene will be lifted up and transfer into different varieties of Streptomyces specific vectors in order to make different transgenic or genetically manipulated Streptomyces.
