This study characterizes metal-responsive TonB-dependent transporters in Pseudomonas aeruginosa using fluorescent reporter plasmids and shows their functional roles and expression patterns in different conditions.

This study identifies PqqU as the primary PQQ importer in P. aeruginosa, showing its essential role in PQQ uptake and metabolic adaptability.

This study shows Salmonella uses exogenous siderophores more at low pH due to reduced endogenous siderophore production, with RpoS regulating this shift.
