Transposon mutagenesis uncovers the genetic landscape of streptomycin susceptibility and implicates SbmA in aminoglycoside uptake in Escherichia coli

Aminoglycosides are critical antibiotics with partially elucidated mechanisms of uptake and action in Gram-negative bacteria. Importantly, although energy-dependent uptake across the inner membrane has been well-established, the specific molecular mechanisms involved have not been definitively identified. To deepen understanding of genetic factors influencing susceptibility and resistance to…
