We have recently described a toxA positive regulatory gene, ptxR. We also proposed the presence of another gene which is adjacent to ptxR and interferes with ptxR function on exotoxin A production. In the presence of a fragment that carries the putative gene, the enhancement in exotoxin A ...
Specific ptxR -deletion mutants in P. aeruginosa strains PAO1 and PA103 were constructed. In comparison with their parent strains, both mutants showed a significant reduction in the level of exotoxin A activity. However, upon extensive subculturing, the level of exotoxin A produced by the PAO...

Iron-regulated transcription of ptxR from the P2 promoter, but not constitutive expression from the P1 promoter, was dependent on the Fur-regulated alternative sigma factor gene pvdS, even under aerobic conditions. Consequently, there are two levels of iron-regulated expression of ptxR. The iron-...
