The Structural Biology of Molecular Recognition by Vancomycin

Abstract

Vancomycin is the archetype among naturally occurring compounds known as glycopeptide antibiotics. Because it is a vital therapeutic agent used world-wide for the treatment of infections with gram-positive bacteria, emerging bacterial resistance to vancomycin is a major public health threat. Recent investigations into the mechanisms of action of glycopeptide antibiotics are driven by a need to understand their detailed mechanism of action so that new agents can be developed to overcome resistance. These investigations have revealed that glycopeptide antibiotics exhibit a rich array of complex cooperative phenomena when they bind target ligands, making them valuable model systems for the study of molecular recognition.
