    The protein

    Protein family

  • [SW|MarR family]

    • Modification

  • senses organic peroxides and NaOCl, released from DNA upon oxidation of an active site cysteine
  • S-bacillithiolated by NaOCl and CHP stress on Cys-15, this results in release from the'' [gene|869E46AECF6249610F8541E403D834284B62171D|ohrA]'' promoter [Pubmed|21749987]
