This gene is a member of the following regulons


PerR regulon

The Fur regulon


Gene


  • Coordinates on the chromosome (coding sequence): 2,449,841 -> 2,450,290
  • Phenotypes of a mutant

  • no growth with glucose and ammonium as single sources of carbon and nitrogen, respectively (due to FsrA-mediated repression of the gltA-gltB operon) PubMed
  • poor frowth on lactate as single carbon source (due to overexpression of FsrA-mediated repression of the lutA-lutB-lutC operon, can be suppressed by inactivation of fsrA or fbpB) PubMed
