Drug-resistant bacteria are becoming harder to treat, pushing scientists to look for new antibiotic targets. Researchers have now discovered that several unrelated viruses disable a key bacterial protein called MurJ, which is essential for building the bacterial cell wall. High-resolution imaging shows these viral proteins lock MurJ into a single position, stopping cell wall construction and leading to bacterial death.
