Development of a whole-cell biosensor for β-lactamase inhibitor discovery

Abstract

The production of β-lactamases by bacterial pathogens endangers antimicrobial therapy, and new inhibitors for β-lactamases are urgently needed. We report the development of a luminescent-based biosensor that quantifies β-lactamase inhibition in a cellular context, based on the activation of transcriptional factor AmpR following the exposure of bacterial cells to β-lactams. This rapid method can account for factors like membrane permeability and can be employed to identify new β-lactamase inhibitors.
