Categories containing this gene/protein

cell division, membrane proteins

This gene is a member of the following regulons

Spo0A regulon

The gene

Basic information

  • Locus tag: BSU15390

Phenotypes of a mutant

  • perturbation of the formation of properly formed division septa
  • less efficient cell division results in longer cells. Electron microscopy reveals strongly distorted division septa.
  • the sepF mutation in combination with a constitutively active form of WalR (WalR-R204C) results in the formation of cell wall-less L-forms PubMed
  • the sepF mutation is synthetically lethal in combination with an ezrA mutation or an ftsA mutation

Database entries

  • DBTBS entry: [1]
  • SubtiList entry: [2]

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • SepF assembles into very large (∼50 nm diameter) rings. These rings are able to bundle FtsZ protofilaments into strikingly long and regular tubular structures reminiscent of eukaryotic microtubules PubMed
  • Protein family: sepF family (according to Swiss-Prot)
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
    • N-terminal amphipatic helix for membrane binding PubMed
    • C-terminal FtsZ-binding domain PubMed
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:

  • KEGG entry: [3]
  • E.C. number:

Additional information

Expression and regulation

  • Sigma factor:
  • Regulation:
    • repressed under conditions that trigger sporulation (Spo0A) PubMed
  • Regulatory mechanism:
  • Additional information:

  • Mutant:
  • Expression vector:
  • lacZ fusion:
  • GFP fusion:
  • two-hybrid system:
  • Antibody:
