Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: binding to the upstream activating sequence in front of the levD gene results in activation of transcription of the levD-levE-levF-levG-sacC operon, bining occurs in the presence of fructose
