Abstract
Peptidoglycan biosynthesis is an essential process in bacteria and is therefore a suitable target for the discovery of new antibacterial drugs. One of the last cytoplasmic steps of peptidoglycan biosynthesis is catalyzed by the integral membrane protein MraY, which attaches soluble UDP- N-acetylmuramoyl-pentapeptide to the membrane-bound acceptor undecaprenyl phosphate. Although several natural product–derived inhibitors of MraY are known, none have the properties necessary to be of clinical use as antibacterial drugs. Here we describe a novel, homogeneous, fluorescence resonance energy transfer–based MraY assay that is suitable for high-throughput screening for novel MraY inhibitors. The assay allows for continuous measurement, or it can be quenched prior to measurement.
