FpvIR control of fpvA ferric pyoverdine receptor gene expression in Pseudomonas aeruginosa: demonstration of an interaction between FpvI and FpvR and identification of mutations in each compromising this interaction.

abstract：:A fusion constructed between the putative attenuator plus the first 219 nucleotides of the ermC (erythromycin resistance) structural gene and a 5' terminally deleted lacZ gene produced a moderate, basal level of beta-galactosidase which was increased by erythromycin addition. Another construction containing an intact ...
