    Phenotypes of a mutant

  • sensitive to H2O2 [pubmed|30954900]
  • reduced viability of [gene|48BCA38E609E443406E03A32D2BB8DA2E9915A71|rarA] [gene|A44D4677FB70BE8F554BF1001A500F817C7DA95F|recA] or [gene|48BCA38E609E443406E03A32D2BB8DA2E9915A71|rarA] [gene|80E6F156764FF30300D034EE6FB44F2DB8338AF3|recO] double mutants [pubmed|32117122]

    • The protein

    Catalyzed reaction/ biological activity

  • inhibits [protein|AF5ADDA2A98EC18BB72A81AA0336E639C0D1F430|PriA]-dependent initiation of [category|SW 3.1.1|DNA replication] [pubmed|29947798]
  • contributes to error-prone DNA repair, links re-initiation of DNA replication with repair-by-recombination by controlling the access of the replication machinery to a collapsed replication fork [pubmed|30954900]
  • contributes to the assembly of RecA nucleoprotein filaments onto single-stranded DNA [pubmed|32117122]

    • Protein family

  • [SW|AAA ATPase family] (according to UniProt)

    • Effectors of protein activity

  • ATPase is stimulated by ssDNAdsDNA junctions or dsDNA ends [pubmed|29947798]
  • ssDNA-dependent ATPase is stimulated by [protein|8DE39680CA7663803A107066FBE9AFFCC77DB72A|SsbA] bound to ssDNA [pubmed|29947798]
