Study Shows How Antibiotic Sets Up Road Block To Kill Bacteria

Scientists have taken a critical step toward the development of new and more effective antibacterial drugs by identifying exactly how a specific antibiotic sets up a road block that halts bacterial growth. The antibiotic, myxopyronin, is a natural substance that is made by bacteria to fend off other bacteria. Scientists already knew that this antibiotic inhibited the actions of an enzyme called RNA polymerase, which sets gene expression in motion and is essential to the life of any cell.
