Adaptive responses to Oxidative Stress: The soxRS and oxyR Regulons

  • Elena Hidalgo
  • Bruce Demple


Along with other environmental changes considered elsewhere in this book, bacteria must cope with changing exposure to oxygen radicals. Escherichia coli meets these challenges by activating complex resistance mechanisms against these radicals. This chapter focuses on the regulatory mechanisms and functions of two key response systems, the soxRS and the oxyR regulons.
