Mining bacterial cell wall biosynthesis with new tools: multitarget screens.
The cytoplasmic steps of peptidoglycan synthesis remain underexplored for the discovery of novel antibiotics. Pathway screens are well suited to screen for novel inhibitors because several targets are tested at once. Whole-cell based assays are easier to set up but they tend to favor identification of compounds that inhibit enzymes that are at the limiting rate in the pathway. Screens that use purified enzymes are optimized to detect with similar probability inhibitors of any of the targets in the pathway. This approach is being used to identify novel promising molecules.
