T3SSipB is a family of pathogenic Gram-negative bacterial proteins that invade human intestinal cells via the type III secretion system translocators. T3SSipB represents the coiled -coil region of the proteins and is shown to be homologous in activity to the pore-forming toxins of other Gram-negative pathogens, such as colicin Ia [1-8].	Domain
