  • [SW|cell division], [SW|essential genes], [SW|membrane proteins]

    • This gene is a member of the following [SW|regulons]

  • [SW|SigH regulon], [SW|WalR regulon]

    • Gene

    Coordinates on the chromosome (coding sequence)
    1,597,832 -> 1,598,980

    Phenotypes of a mutant

  • essential [Pubmed|12682299], but dispensible in [protein|search|L-forms] [Pubmed|25358088]

    • The protein

    Protein family

  • ftsZ family (according to Swiss-Prot)

    • Effectors of protein activity

  • Z ring formation is inhibited upon binding of [protein|search|MciZ] to FtsZ
  • bundling of FtsZ protofilaments into strikingly long and regular tubular structures reminiscent of eukaryotic microtubules requires the prior formation of large ring polymers of [protein|search|SepF] [Pubmed|21224850]
  • interaction with [protein|search|UgtP] inhibits [protein|search|FtsZ] filament formation [Pubmed|22931116]
  • FtsZ polymerization is inhibited by interaction with [protein|search|MinC] [Pubmed|23577149]
  • Z ring formation requires [protein|search|PdhA] in a pyruvate-dependent manner [Pubmed|24825009]

    • Structure

  • [PDB|2VAM]
  • [PDB|2RHL] (dimer with GDP)
  • [PDB|4U39] ([protein|search|FtsZ]-[protein|search|MciZ] complex) [Pubmed|25848052]

    • [SW|Localization]

  • septal at the cell membrane [Pubmed|20566861]
  • septal localization partially depends on the proton motive force [Pubmed|20566861]
  • [protein|search|Noc] and the Min system ensure the efficient utilization of the division site at midcell in by ensuring [FtsZ|search|Z ring] placement [Pubmed|22457634]
  • [protein|search|FtsZ] is anchored to the cell membrane by either [protein|search|FtsA] or [protein|search|SepF] [Pubmed|24218584,16159787]
