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

Database entries

  • Structure
  • Swiss prot entry
  • KEGG entry

Expression and regulation

  • Operon: gltC [3]
  • Sigma factor: SigA [4]
  • Regulation: autoregulation by GltC [5]
  • Regulatory mechanism: autorepression

Biological materials

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