    Phenotypes of a mutant

  • 60-fold increased mutation rate [Pubmed|23882084]
  • a ''[gene|D5275ECDC2A70FBAC2CA5980F04B272C3328FC90|rnhB] [gene|E2A8B04CD729332F9E6A13195181983F751F2F25|mutS]-[gene|A86A013EDCE59D7EF84FB836A751E66C58CADF45|mutL]'' mutant is not viable [Pubmed|23882084]

    • The protein

    Catalyzed reaction/ biological activity

  • MutS recognizes mismatches in the DNA and recruits [protein|A86A013EDCE59D7EF84FB836A751E66C58CADF45|MutL] to the site of mismatch recognition

    • Protein family

  • DNA mismatch repair mutS family (according to Swiss-Prot)

    • Structure

  • [PDB|1NG9] (from ''E. coli'', 39% identity) [Pubmed|12554674]

    • [SW|Localization]

  • forms foci at midcell position, the frequency of foci increases upon mismatch formation [Pubmed|21958350]
  • replication-active region of the DNA, via [protein|83E05071DEC874248D3E96B8F3A093C65939B314|DnaN] [Pubmed|23228104]
  • MutS dynamics are heterogeneous in cells, with one MutS population exploring the nucleoid rapidly, while another MutS population moves to and transiently dwells at the [SW|replisome] region, even in the absence of appreciable mismatch formation [Pubmed|26575623]
