This gene is a member of the following regulons

SigH regulon

The gene

Basic information

  • Locus tag: BSU28030

Phenotypes of a mutant

essential PubMed, the mutation can be suppressed by inactivation of ponA, ptsI, ccpA PubMed or addition of 5 mM Magnesium to the growth medium PubMed

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • forms straight filaments in a heterologous system PubMed
    • polymerizes in the presence of millimolar divalent cations, binds and hydrolyzes GTP and ATP PubMed
  • Protein family: ftsA/mreB family (according to Swiss-Prot)

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity:
  • Localization:
    • forms helical structures close to the inner surface of the cytoplasmic membrane PubMed
