3.A.1.14.3
Iron (Fe3+)-hydroxamate (ferrichrome, coprogen, aerobactin, ferrioxamine B, schizakinen, rhodotorulic acid) porter, albomycin porter.  A FtsZ inhibitor can utilize siderophore-ferric iron uptake transporter systems, FepA, CirA (outer membrane transporters) and FhuBC (inner membrane transporter) for activity against Gram-negative bacterial pathogens (Bryan et al. 2024).
