    Phenotypes of a mutant

  • reduced natural transformation with plasmid or chromosomal DNA [Pubmed|23284295]
  • 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|24285298]

    • The protein

    Catalyzed reaction/ biological activity

  • modulates the "length or packing" of a [protein|A44D4677FB70BE8F554BF1001A500F817C7DA95F|RecA] filament, thereby [protein|144E7D10740C5F146403612B8A0C88E02FB9C572|RecX] facilitates the initiation of recombination and increases recombination across species [Pubmed|23284295]

  • inhibits stable [protein|A44D4677FB70BE8F554BF1001A500F817C7DA95F|RecA] nucleation and polymerization on ssDNA [pubmed|28911099]
  • induces [protein|A44D4677FB70BE8F554BF1001A500F817C7DA95F|RecA] nucleoprotein filament depolymerization [pubmed|28911099]
  • promotes a net [protein|A44D4677FB70BE8F554BF1001A500F817C7DA95F|RecA] disassembly from viral ssDNAs not homologous to the host genome [pubmed|31876108]
