Abstract

Understanding the molecular mechanisms of bacterial pathogenesis and virulence is of great importance from both an academic and clinical perspective, especially in view of an alarming increase in bacterial resistance to existing antibiotics and antibacterial agents. Use of small molecules to dissect the basis of these dynamic processes is a very attractive approach due to their ability for rapid spatiotemporal control of specific biochemical functions. Activity-based protein profiling (ABPP), employing small molecule probes to interrogate enzyme activities in complex proteomes, has emerged as a powerful tool to study bacterial pathogenesis. In this chapter, we present a set of ABPP methods to identify and analyze enzymes essential for growth, metabolism and virulence of different pathogens including S. aureus and L. monocytogenes using natural product-inspired activity-based probes.
