We've tried this system before. Although I don't have any sequence 
information I can tell you that it is produced commercially by Novagen.
The plasmid is a derivative of  pACYC184. You co-transform with your
normal expression vector (pSW1 has tet resistance) and induce the BRP
expression with mitomycin C. You want a different inducer to your desired
protein because you only want low levels of BRP - too much and you kill
your cells rather than just making them leaky. 

Hope this helps
