Scientists discover a bacterial kill switch and it could change the fight against superbugs

February 28, 2026

Researchers have identified a bacterial 'kill switch' that could revolutionize the treatment of superbugs. By targeting a vital protein called MurJ, essential for bacterial cell wall construction, certain viruses can effectively halt the growth of drug-resistant bacteria, potentially leading to new antibiotic developments.

Viruses may hold the blueprint for next-generation antibiotics—by revealing how to shut down a bacterial lifeline called MurJ. Here, three distinct phage Sgl proteins lock the flippase MurJ in an outward-facing state, providing a template for antibiotic discovery
