Schematic of the “Trojan horse” strategy in Gram-negative bacteria. Antibiotic bound-siderophores bind to outer-memberane receptors which help their transport to the periplasmic space upon interaction with the Ton complex. In the periplasm, siderophores are sequestered by periplasmic-binding proteins which deliver them to ATP-dependent transporters which help their entrance into the cell. Antibiotics which would not pass cellular membranes otherwise, can therefore be released.
