  regulatory mechanism

  • [protein|857EF1AC54DEA0690C01B7F8CEFFD16312C58F20|TnrA]: activation, [Pubmed|12823818], in [regulon|857EF1AC54DEA0690C01B7F8CEFFD16312C58F20|TnrA regulon]
  • [protein|90ACE0DECA58D3C1A55E135120F7A0C1C920571C|CodY]: repression, no derepression occurs, however, in a [protein|90ACE0DECA58D3C1A55E135120F7A0C1C920571C|CodY] mutant, due to increased repression by [protein|F7FD94CE7AB290FBFD3A9B88F204961668F9B42C|ScoC] [Pubmed|25966844], in [regulon|90ACE0DECA58D3C1A55E135120F7A0C1C920571C|CodY regulon]

  regulation

  • expressed in the absence of good nitrogen sources (glutamine or ammonium) ([protein|search|TnrA]) [Pubmed|12823818]
