Plasmids expressing T7 epitope-tagged ExbB or ExbD proteins and the untagged partner proteins. In each case, the T7-tagged protein is expressed from the T7 promoter. T7 RNA polymerase is induced by 0.01 mM IPTG from λDE3 inserted into the host cell chromosome. The partner protein is expressed from the exb promoter. (A) pKP339 (T7-ExbB) and the compatible plasmid pKP360 (ExbD). (B) pKP323 (T7-ExbD) and the compatible plasmid pKP361 (ExbB). Expected protein products are illustrated to the right of each plasmid set.
