Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity: transport and phosphorylation of glucose, receives a phosphate from HPr at the IIA domain (His-620), the phosphate group is then transferred to the IIB domain (Cys-461) an finally to the incoming glucose. In the absence of glucose, PtsG phosphorylates and thereby inactivates the transcriptional antiterminator GlcT.
  • Protein family: PTS permease, glucose permease (Glc) family PubMed, PTS enzyme II
  • Paralogous protein(s):

    • PTS EIIC domain ( 1-424)
    • PTS EIIB domain (439–520)
    • PTS EIIA domain (568–672)
  • Modification: transient phosphorylation (HPr-dependent) on His-620, then internal phosphotransfer from His-620 to Cys-461
