Bacterial cell-to-cell communication ('quorum sensing') is mediated by structurally diverse, small diffusible signal molecules which regulate gene expression as a function of cell population density. Many different Gram-negative animal, plant and fis...
The critical role played by antimicrobial peptides (AMPs) in mammalian innate immunity is increasingly recognized. Bacteria differ in their intrinsic susceptibility to AMPs, and the relative resistance of some important human pathogens to these defen...
The review summarizes for the first time the current concepts of the role of tyrosine phosphorylation in regulation of signal transduction pathways in unicellular eukaryotes. Evolutionary concepts are developed about the origin of protein tyrosine ki...
The MarR (multiple antibiotic resistance regulator) family of prokaryotic transcriptional regulators includes proteins critical for control of virulence factor production, bacterial response to antibiotic and oxidative stresses and catabolism of envi...
