Abstract

Expression of the inner membrane protein FoxB (PA2465) of Pseudomonas aeruginosa in mutants of Sinorhizobium meliloti that are defective in the utilization of ferrichrome, ferrioxamine B, and schizokinen resulted in the restoration of siderophore utilization. Mutagenesis of foxB in P. aeruginosa did not abolish siderophore utilization, suggesting that the function is redundant.
