This report describes the development and use of TnKnXSp, a selectable broad-host-range reporter transposon with a promoterlessaphA gene. Insertion of TnKnXSpinto the chromosome of a kanamycin-susceptible bacterium confers resistance to kanamycin only ifaphA is transcribed from an active promoter adjacent to the insertion site. We designed TnKnXSpas a tool for iden.jpeg"ying environmentally regulated promoters in bacteria and developed general methods for initial characterization of any TnKnXSpintegrant. To iden.jpeg"y putative iron-regulated promoters inCorynebacterium diphtheriae, we constructed TnKnXSpintegrants and iden.jpeg"ied a subgroup that expressed kanamycin resistance under low-iron, but not high-iron, conditions. We characterized representative integrants with this phenotype, located the TnKnXSpinsertion in each, and demonstrated that transcription ofaphA was repressed under high-iron vs. low-iron growth conditions. We also demonstrated that TnKnXSpcan be used in bacteria other thanC. diphtheriae, includingEscherichia coliandBacillus subtilis. Our findings validate TnKnXSpas a useful tool for iden.jpeg"ying environmentally regulated promoters in bacteria.
