OxyR

Introduction

Illustration of OxyR Activation

OxyR, a positive regulator of hydrogen peroxide-inducible genes in E. coli. The OxyR transcription factor regulates the H₂O₂ response of E. coli. H₂O₂ oxidizes OxyR Cys199 to an R-SOH that reacts with Cys208 in an intramolecular disulphide bond.

(A)Reduced Form: Inactive
(B)Oxidized Form: Activated by ROS
