How does ribosome research help fight antibiotic resistance?
Ribosome research is directly relevant because many antibiotics—like tetracyclines, macrolides, and aminoglycosides—target the ribosome. Our atomic structures show exactly where these drugs bind and how they block protein synthesis. For example, we saw how erythromycin plugs the exit tunnel, preventing the growing peptide chain from emerging. With antibiotic resistance rising, we need new drugs that bind to different sites or overcome resistance mutations. The structure tells us how it works—we can design molecules that fit into the ribosome's crevices more tightly or evade common resistance mechanisms. My lab has studied how resistance mutations alter the binding pocket, guiding the development of next-generation antibiotics. This is a clear example where fundamental molecular biology translates into practical medical solutions.
