    Phenotypes of a mutant

  • over-replication during sporulation [Pubmed|19682252]

    • The protein

    Catalyzed reaction/ biological activity

  • interacts with [protein|6740108089F13116F200C15F35C2E7561E990FEB|DnaA] and displaces it from the replication origin, resulting in inhibition of replication [Pubmed|19682252]

    • Structure

  • [PDB|4TPS] (in complex with N-terminal domain of [protein|6740108089F13116F200C15F35C2E7561E990FEB|DnaA]) [Pubmed|25041308]

    • [SW|Localization]

  • accumulates at the [SW|replisome] in sporulating cells (perhaps in [protein|6740108089F13116F200C15F35C2E7561E990FEB|DnaA]-dependent manner) [Pubmed|25041308]
