RESUMO
We investigated the regulation of the psbA and pvdA pyoverdine biosynthesis genes, which encode the l-ornithine N5-oxygenase homologues in Pseudomonas strain B10 and Pseudomonas aeruginosa PAO1, respectively. We demonstrate that pyoverdineB10, as the end product of its biosynthetic pathway, is a key participant of the control circuit regulating its own production in Pseudomonas strain B10. In P. aeruginosa PAO1, however, pyoverdinePAO1 has no apparent role in the positive regulation of the pvdA gene.
