EMBL Hamburg’s Wilmanns and Kosinski groups have determined the detailed structure of a bacterial protein complex critical for tuberculosis infection.

Tuberculosis (TB) is one of the top ten causes of death worldwide. In 2017, 10 million people around the world fell ill with TB and 1.3 million died. The genome of the bacterium that causes TB holds a special toxin-antitoxin system with spectacular action: once the toxin is activated, all bacterial cells die, stopping the disease. An international research team co-led by the Wilmanns group at EMBL in Hamburg investigated this promising feature for therapeutic targets. They now share the first high-resolution details of the system in Molecular Cell.
