Additional information

The protein

Basic information/ Evolution

  • Catalyzed reaction/ biological activity:
  • Protein family: PtsH,HPr family
  • Paralogous protein(s): HPr

Extended information on the protein

  • Kinetic information:
  • Domains: HPr domain (1–85)
  • Modification: phosphorylation on Ser46 by HPrK PubMed
