    Phenotypes of a mutant

  • essential, the mutation can be suppressed by second-site mutations in ''[gene|49E8BFEC1CAB77DD91E0ED0791EBD480E4871239|addA]'' or ''[gene|55A1EF8A10CB398CCD3FDD06D9483FE0DCE31C64|addB]'' [Pubmed|22984257], non-essential according to [Pubmed|28189581]

    • The protein

    [SW|Localization]

  • evenly distributed throughout the cytosol in growing cells [Pubmed|22984257]
  • forms a single focus on the nucleoid upon induction of DNA damage [Pubmed|22984257]
