Schematic representation of CosR regulatory network in C. jejuni. The detoxification flow of oxidants by oxidative stress resistance enzymes (gray boxes) is drawn with dashed lines, and the transcriptional regulators (CosR, Fur, PerR, and CmeR) are boxed in ovals. The regulation by CosR is indicated with double-strand lines, and positive and negative regulations by CosR are marked with arrowheads and flat-line heads, respectively. CosR is indispensable to Campylobacter's viability, although its regulation mechanism is not known. This is indicated with a dashed double-strand line.
