The gene

Basic information

  • Locus tag: BSU23520

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
