This gene is a member of the following regulons

SigD regulon

The gene

Basic information

  • Locus tag: BSU14010

Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
  • Protein family:
  • Paralogous protein(s): CheW (N-terminal domain of CheV)

Extended information on the protein

  • Kinetic information:
  • Domains: N-terminal CheW-like domain, C-terminal two-component receiver domain PubMed
  • Modification: the C-terminal two-component receiver domain is phosphorylated on a Asp residue by CheA PubMed
  • Cofactor(s):
  • Effectors of protein activity:
  • Localization:
    • forms lateral clusters (phosphorylated form), but in the presence of high asparagine concentration (non-phosphorylated form) there is a reversible re-localization to the poles of the cell PubMed

Database entries

  • Structure:
  • KEGG entry: [3]
  • E.C. number:

Additional information

Expression and regulation

  • Regulation:
  • Regulatory mechanism:
  • Additional information:
    • in minimal medium, CheV is present with 7,500 +/- 2,000 molecules per cell PubMed
    • number of protein molecules per cell (minimal medium with glucose and ammonium): 1117 PubMed
    • number of protein molecules per cell (complex medium with amino acids, without glucose): 1764 PubMed
