    • regulation

  • expression during spore [SW|germination] is strongly reduced under conditions of osmotic stress [Pubmed|27766092]
  • induced by iron starvation (second wave to allow iron scavenging from the environment) ([protein|F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|Fur]) [pubmed|29133393]
  • expression of the operon is strongly induced at the beginning of [SW|biofilm formation] [pubmed|31113899]

    • 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]
