Expanding Aminoglycoside Resistance Enzyme Regiospecificity by Mutation and Truncation.

ABSTRACT: Aminoglycosides (AGs) are broad-spectrum antibiotics famous for their antibacterial activity against Gram-positive and Gram-negative bacteria, as well as mycobacteria. In the United States, the most prescribed AGs, including amikacin (AMK), gentamicin (GEN), and tobramycin (TOB), are vital components of the treatment for resistant bacterial infections. Arbekacin (ABK), a semisynthetic AG, is widely used for the treatment of resistant Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus in Asia. However, the rapid emergence and development of bacterial resistance are limiting the clinical application of AG antibiotics. Of all bacterial resistance mechanisms against AGs, the acquisition of AG-modifying enzymes (AMEs) by bacteria is the most common. It was previously reporte
