Iron starvation induced by vacidobactin A impairs the growth of pyoverdine-deficient Pseudomonas aeruginosa
VacA, a siderophore produced by the soil bacterium Variovorax paradoxus, suppresses P. aeruginosa growth by limiting iron availability, particularly in strains deficient in pyoverdine production, and the synergy between vacidobactin A and thiostrepton illustrates how siderophore systems integrate with other cellular vu...
