Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
    • transcription activation of the gabT-gabD operon in the presence of GABA and PLP, transcription repression of gabR PubMed
  • Paralogous protein(s): none, but there are 7 members of the MocR/ GabR family in B. subtilis

Extended information on the protein

  • Kinetic information:
  • Domains:
    • N-terminal DNA-binding helix-turn-helix motif (corresponding to domains of the GntR family) PubMed
    • C-terminal domain is homologous to PLP-binding large domain of aminotransferases PubMed
  • Modification:
  • Effectors of protein activity:
    • activation of gabT-gabD expression is triggered by gamma-amino butyrate and pyridoxalphosphate PubMed
