Puroomycin is an antibiotic that acts as a chain terminator during protein synthesis. It binds to the ribosome and inhibits the addition of amino acids to the growing protein chain by causing premature termination of protein synthesis. It is a transcription inhibitor and a potent inhibitor of protein biosynthesis. Puroomycin is often used in molecular biology research to study the translation process in eukaryotes and to demonstrate the concept of a ribosome.
