Acyl homoserine lactones (acyl-HSLs) are important intercellular signaling molecules used by many bacteria to monitor their population density in quorum-sensing control of gene expression. These signals are synthesized by members of the LuxI family of proteins. To understand the mechanism of acyl-HSL synthesis we have purified the Pseudomonas aeruginosa RhlI protein and analyzed the kinetics of...
Listeriolysin O (LLO), an essential virulence determinant of Listeria monocytogenes, is a pore-forming toxin whose primary function is to facilitate cytosolic bacterial replication by breaching the phagosomal membranes, which is critical for the pathogen to evade host immune recognition. The critical role of LLO in the virulence of L. monocytogenes renders it an ideal target for designing novel...
As an essential constituent of the outer membrane of Gram-negative bacteria, lipopolysaccharide contributes significantly to virulence and antibiotic resistance. The lipopolysaccharide biosynthetic pathway therefore serves as a promising therapeutic target for antivirulence drugs and antibiotic adjuvants. Here we report the structural-functional studies of D-glycero-β-D-manno-heptose 7-phosphat...
Since the discovery of penicillin, antibiotics have been of critical importance in the control of infectious diseases. However, the extensive use and misuse of antibiotics during recent decades led to the widespread development and distribution of resistance to multiple drugs among bacteria. With the alarming levels of antibiotic resistance and the difficulties associated with discovering novel...
