The protein

Basic information/ Evolution

• Catalyzed reaction/ biological activity: Protein EIIA N(pi)-phospho-L-histidine + protein EIIB = protein EIIA + protein EIIB N(pi)-phospho-L-histidine/cysteine (according to Swiss-Prot)

• Protein family: transcriptional antiterminator bglG family (according to Swiss-Prot), Attention: this is wrong: LicR is a transcription activator, the similarity to the BglG family is limited to the PTS-regulation domains
