Distinct transcriptional logics of catechol siderophore transporters in Pseudomonas aeruginosa for efficient iron acquisition.
With 21 outer-membrane transporters dedicated to iron acquisition, Pseudomonas aeruginosa possesses an extensive toolkit for securing this essential nutrient, but activates the expression only of those relevant to its immediate environment. Eighteen of these pathways rely on siderophores, two produced by P. aeruginosa...
