This gene is a member of the following regulons

The gene

Basic information

  • Locus tag: BSU08520

Phenotypes of a mutant

  • reduced natural tranformation with plasmid or chromosomal DNA PubMed
  • drastically reduced survival of mature dormant spores after exposure to ultrahigh vacuum desiccation and ionizing radiation that induce single strand (ss) DNA nicks and double-strand breaks (DSBs) PubMed

  • SubtiList entry: [2]

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • modulates the "length or packing" of a RecA filament, thereby RecX facilitates the initiation of recombination and increases recombination across species PubMed
  • Protein family: recX family (according to Swiss-Prot)
  • Paralogous protein(s):

  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
  • Localization:
    • forms foci on the nucleoid upon DNA damage PubMed
