DNA repair/ recombination

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

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)
