Monitoring Drug-Protein Interactions in the Bacterial Periplasm by Solution Nuclear Magnetic Resonance Spectroscopy
Résumé
The rapid spread of antimicrobial resistance across bacterial pathogens poses a serious risk to the efficacy and sustainability of available treatments. This puts pressure on research concerning the development of new drugs. Here, we present an in-cell NMR-based research strategy to monitor the activity of the enzymes located in the periplasmic space delineated by the inner and outer membranes of Gram-negative bacteria. We demonstrate its unprecedented analytical power in monitoring in situ and in real time (i) the hydrolysis of β-lactams by β-lactamases, (ii) the interaction of drugs belonging to the β-lactam family with their essential targets, and (iii) the binding of inhibitors to these enzymes. We show that in-cell NMR provides a powerful analytical tool for investigating new drugs targeting the molecular components of the bacterial periplasm.
