    regulatory mechanism

  • [regulon|stringent response|stringent response]: negative regulation, in [regulon|stringent response|stringent response]
  • [protein|E15E9F88B0E03FE8834C646369D2F4B4E713EF41|CitB]: mRNA binding, in [regulon|E15E9F88B0E03FE8834C646369D2F4B4E713EF41|CitB regulon]

    • regulation

  • [protein|search|RelA] dependent downregulation (Class I) during stringent response [Pubmed|11948165]

    • additional information

  • the presence of an iron-responsive element bound by [SW|CitB] between ''[SW|feuA]'' and ''[SW|feuB]'' suggests iron-dependent regulation by [SW|CitB] [Pubmed|10468622]
