Dennis H. Kim and Watson J. Lees Biochemistry 2025 DOI: 10.1021/acs.biochem.4c00522 The antibiotic fosfomycin is an epoxy-phosphonate natural product with a broad spectrum of antibacterial activity and distinct mechanism of action that has been in clinical use for 50 years. Fosfomycin is an irreversible covalent inhibitor of UDP-GlcNAc enolpyruvyl transferase (MurA), which catalyzes the first committed step in bacterial peptidoglycan biosynthesis.
