Identification of Brucella abortus OxyR and its role in control of catalase expression

Academic Article


  • We report the cloning and sequencing of the Brucella abortus oxyR homolog and provide evidence that the transcription product of this gene binds to the B. abortus catalase promoter region. A gene replacement/deletion Brucella oxyR mutant exhibits increased sensitivity to prolonged exposure to H2O2 and is unable to adapt to H2O2 in the environment.
