Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: transcription activation of the gltAB operon
  • Protein family: LysR-type transcription regulator
  • Paralogous protein(s): none, but there are 19 members of the LysR family in B. subtilis

Extended information on the protein

  • Kinetic information:
  • Domains: DNA-binding helix-turn-helix motif: AA 18 ... 37
  • Modification:
  • Effectors of protein activity: 2-oxoglutarate
  • Interactions:
    • GltC-RocG, This interaction takes place in the presence of glutamate. It prevents the transcription activation of the gltAB operon. Note that RocG expression is strongly regulated. <ref>Commichau et al. (2007)</ref>
  • Localization:

  • Structure:

Additional information

Expression and regulation

  • Operon: gltC
  • Sigma factor: SigA
  • Regulation: autoregulation by GltC
  • Regulatory mechanism: autorepression
  • Additional information:

Biological materials

  • Mutant:
  • Expression vector:
  • lacZ fusion:
  • GFP fusion:
  • Antibody: available in Stülke lab
