    Phenotypes of a mutant

  • synthetic lethal phenotype with a ''[gene|672EA84D7725BE21F649DF30A11EB4E0EDFC3925|ftsA]'' mutation [Pubmed|18776011]; synthetic sick phenotype when combined with an ''[gene|B317D7E51824DD70EF84E4D5D7290D601BF4FAB6|ezrA]'' mutation [Pubmed|18363795], although this seems controversial [Pubmed|18776011]
  • reduced growth at high salt [Pubmed|25845974]

    • The protein

    Catalyzed reaction/ biological activity

  • activates [protein|23FF4A00C36EC1B7297F51A9EF3579B41F0B7EBA|PrkC] [Pubmed|25845974]

    • Paralogous protein(s)

  • [protein|A8C0C2B7BCA6FFFF3811402D683FB7B99F7120A4|DivIVA]

    • [SW|Domains]

  • contains a [protein|A8C0C2B7BCA6FFFF3811402D683FB7B99F7120A4|DivIVA]-like N-terminal domain

    • Modification

  • phosphorylation on Thr-75 by [protein|23FF4A00C36EC1B7297F51A9EF3579B41F0B7EBA|PrkC] [Pubmed|25845974,17218307]

    • Structure

  • [PDB|4UG3] (N-terminal domain, aa 1-68) [Pubmed|26575090]
  • [PDB|5AN5] (C-terminal domain, aa 76-98) [Pubmed|26575090]
  • GpsB is hexameric (trimer of dimers) [Pubmed|26575090]

    • [SW|Localization]

  • dynamic, shuttles between lateral membrane and the divison septum [Pubmed|18363795], localizes to the divisome after Z-ring formation [Pubmed|18776011]
