Oxidative Stress in Shiga Toxin Production by Enterohemorrhagic Escherichia coli

Figure 3

The - regions of phage λ and Shiga toxin-converting phage 933W. Structural elements of each promoter are indicated, and , , and operator sequences are marked. The OxyR binding to the λ- region (demonstrated experimentally [26]) is shown as a solid oval, and a putative (not verified experimentally) OxyR binding to the 933W - region is suggested by a dashed oval.
