This gene is a member of the following regulons
The Fur regulon
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
- transcription profile of a fur mutant strain: GEO PubMed
