  • Protein family:
  • Paralogous protein(s): GapB

Extended information on the protein

  • Kinetic information:
  • Domains:
  • Modification: Phosphorylation (STY)
  • Effectors of protein activity:
  • Interactions:
    • GapA-PtsH: HPr(Ser-46-P) binds GapA resulting in a slight inhibition of enzymatic activity.
    • GapA-Crh: Crh(Ser-46-P) binds GapA resulting in a slight inhibition of enzymatic activity.
  • Localization: membrane and cytoplasm

Database entries

  • Structure:
    • 3CMC (from Geobacillus stearothermophilus)
