It is well established that high-affinity zinc importers play essential roles in bacterial virulence, but the studies described by Moreau et al. in this issue (G. B. Moreau, A. Qin, and B. J. Mann, J Bacteriol 200:e00587-17, 2018, https://doi.org/10.1128/JB.00587-17) demonstrate that we probably still have much to learn about how these transporters function and how the genes that encode them are regulated in different bacterial pathogens.
