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

Database entries

• Structure

• Swiss prot entry

• KEGG entry

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>
