The gene

Basic information

  • Locus tag: BSU18460

Phenotypes of a mutant

gltC mutants are auxotrophic for glutamate.

Database entries

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

Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: transcription activation of the gltA-gltB operon PubMed
  • Protein family: glutamate synthase family (according to Swiss-Prot) LysR-type transcription regulator PubMed
  • 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:
  • Cofactor(s):
  • Effectors of protein activity: 2-oxoglutarate stimulates transcription activation, glutamate inhibits transcription activation PubMed
  • Interactions:
    • GltC-RocG, This interaction takes place in the presence of glutamate. It prevents the transcription activation of the gltA-gltB operon. Note that RocG expression is strongly regulated by carbon and nitrogen sources, respectively. PubMed
  • Localization:

Database entries

  • Structure:
  • KEGG entry: [3]

Additional information

Expression and regulation

  • Regulation: autoregulation by GltC
  • Regulatory mechanism: autorepression
  • Additional information:
