Categories containing this gene/protein

proteolysis, transcription factors and their control, general stress proteins (controlled by SigB), heat shock proteins, phosphoproteins

This gene is a member of the following regulons

CtsR regulon, SigB regulon

The CtsR regulon

The gene

Basic information

  • Locus tag: BSU00830

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: ctsR family (according to Swiss-Prot)
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification:
    • phosphorylation of a tyrosine residue by McsB PubMed
    • recently, it was reported that CtsR is phosphorylated by McsB on Arg-62 rather than on a tyrosine residue PubMed
  • Cofactor(s):
  • Effectors of protein activity:
    • CtsR is inactivated by heat, heat sensing requires Gly-64 PubMed
    • non-phosphorylated McsB targets CtsR for degradation PubMed
    • regulated proteolysis by ClpP/ClpC PubMed
  • Localization:

Database entries

  • Structure: 3H0D (complex with a 26bp DNA duplex, from Geobacillus stearothermophilus) PubMed
  • KEGG entry: [3]
  • E.C. number:

Additional information

Expression and regulation

  • Regulatory mechanism:
  • Additional information: the mRNA is very stable (half-life > 15 min) PubMed

Biological materials

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