Oligonucleotides were synthesized by Alta Bioscience, the University of Birmingham; or MWG Biotech, Germany. The DNA sequence of all mutants and cloned PCR products were confirmed by sequencing using a PE Applied Biosystems Big Dye version 2.0 sequencing kit according to the manufacturer’s protocol, followed by analysis on an ABI 3700 sequencer in the Functional Genomics Laboratory, School of Biosciences, the University of Birmingham. The primers used for sequencing were: pMUforward and pMUreverse, complementary to the sequences flanking the multiple cloning site of pMU2385, and PbrApe for pMapbrR/PpbrA clones (Table 2).
