    Phenotypes of a mutant

  • [protein|632C661255DD9C2865CB2F9D68A805997A833BCB|RpoE] is essential for cell survival when facing a competing strain in changing environment [Pubmed|23543716]

    • The protein

    Catalyzed reaction/ biological activity

  • binds to DNA immediately upstream of the promoter element at A-rich sequences on the abrB and rrnB1 promoters and facilitates open complex formation [Pubmed|26546673]
  • represses expression of ''[gene|29D91115BB3AC03538D618E54A5A57F92777EFF6|spo0B]'' [Pubmed|27679485]

    • Protein family

  • rpoE family (single member, according to UniProt)

    • [SW|Domains]

  • HARE-HTH domain (aa 15-81) (according to UniProt)

    • Structure

  • [PDB|2M4K] (full-length protein) [Pubmed|23868186]
  • [PDB|2KRC] (N-terminal domain) [Pubmed|20310067]

    • [SW|Localization]

  • closely associated with [SW|RNA polymerase] involved in transcribing both mRNA and rRNA operons [Pubmed|20724389]
