The locus of enterocyte effacement (LEE) is essential for virulence of enterohaemorrhagic Escherichia coli (EHEC) and enteropathogenic E. coli (EPEC). The 41 genes of the LEE encode type III secretion system proteins and three associated regulators: Ler, GrlA and GrlR. Ler is a positive regulator for most of the LEE operons, including grlRA. GrlA controls(More)
The Type IV Secretion System (T4SS) is the only bacterial secretion system known to translocate both DNA and protein substrates. The VirB/D4 system from Agrobacterium tumefaciens is a typical T4SS. It facilitates the bacteria to translocate the VirD2-T-DNA complex to the host cell cytoplasm. In addition to protein-DNA complexes, the VirB/D4 system is also(More)
