The gene

Basic information

  • Locus tag: BSU33950

Phenotypes of a mutant

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: transcription repression of the glycolytic gapA operon
  • Protein family: sorC transcriptional regulatory family (according to Swiss-Prot)
  • Paralogous protein(s):

Extended information on the protein

  • Kinetic information:
  • Domains:
    • DNA binding domain (H-T-H motif) (37–56)
  • Modification:
  • Cofactor(s):
  • Effectors of protein activity: fructose 1.6-bisphosphate PubMed and dihydroxyacetone phosphate, glucose-6-phosphate and fructose-6-phosphate PubMed act as inducer and result in release of CggR from the DNA
  • Interactions:
    • active as dimer (according to PubMed)
  • Localization: cytoplasma PubMed

Database entries

  • Structure: 2OKG ( effector binding domain), 3BXH (in complex with fructose-6-phosphate), complex with Fructose-6-Phosphate NCBI, effector binding domain NCBI
  • KEGG entry: [3]

Additional information

Expression and regulation

  • Regulation:
    • expression activated by glucose (77-fold) (CggR) PubMed
  • Regulatory mechanism:
  • Additional information:
    • The primary mRNAs of the operon are highly unstable. The primary mRNA is subject to processing at the very end of the cggR open reading frame. This results in stable mature gapA and gapA-pgk-tpiA-pgm-eno mRNAs. PubMed The processing event requires the RNase Y PubMed.
    • The intracellular concentration of CggR is about 230 nM (according to PubMed).
    • The accumulation of the cggR-gapA mRNA is strongly dependent on the presence of the YkzW peptide, due to stabilization of the mRNA PubMed.

Biological materials

  • Expression vector: pGP705 (N-terminal His-tag, in pWH844), available in Stülke lab
  • GFP fusion:
  • Antibody: available in Stülke lab
