SUMMARY Among bacterial toxin/antitoxin (TA) systems, to date no antitoxin has been identified that functions by cleaving toxin mRNA. Here we demonstrate YjdO (renamed GhoT) is a membrane lytic peptide that causes ghost cell formation (lysed cells with damaged membranes) and increases persistence (persister cells are tolerant to antibiotics without(More)
MqsR-controlled colanic acid and biofilm regulator (McbR, also known as YncC) is the protein product of a highly induced gene in early Escherichia coli biofilm development and has been regarded as an attractive target for blocking biofilm formation. This protein acts as a repressor for genes involved in exopolysaccharide production and an activator for(More)
The Escherichia coli protein BdcA (previously referred to as YjgI) plays a key role in the dispersal of cells from bacterial biofilms, and its constitutive activation provides an attractive therapeutic target for dismantling these communities. In order to investigate the function of BdcA at a molecular level, we integrated structural and functional studies.(More)
