Selective uptake of a DNA gyrase poison kills Mycobacterium tuberculosis

Photorhabdus noenieputensis (a gut microbiota symbiont of nematodes) produces a macrocyclic antibiotic, evybactin, that selectively kills Mycobacterium tuberculosis (Mtb). The Mtb membrane transporter BacA imports evybactin into the cell, where it binds to DNA gyrase and causes cell death.
