These proteins are subject to a phosphorylation event. Most often, protein phosphorylation affects the conformation of the protein resulting in changes in biological activity and/ or localization.

Phosphoproteins in B. subtilis

Phosphorylation on an Arg residue

Phosphorylation on a His residue=

  • PTS proteins
    • Enzyme I: autophosphorylated using phosphoenolpyruvate as phosphate donor
    • HPr: phosphorylated by Enzyme I
    • PtsG: glucose permease, EIICBA: phosphorylated by HPr
    • GamP: glucosamine permease, EIICBA: phosphorylated by HPr
    • MtlA, MtlF: mannitol permease: phosphorylated by HPr
    • GmuA, GmuB, GmuC: galactomannan permease: phosphorylated by HPr
    • TreP: trehalose permease: phosphorylated by HPr
    • MalP: maltose permease: phosphorylated by HPr
    • FruA: fructose permease: phosphorylated by HPr
    • ManP: mannose permease: phosphorylated by HPr
    • LevD, LevE, LevF, LevG: fructose permease: phosphorylated by HPr
    • LicA, LicB, LicC: lichenan permease: phosphorylated by HPr
    • BglP: ß-glucoside permease
    • YpqE: unknown EIIA component: phosphorylated by HPr
    • YyzE: unknown PTS protein
  • Non-PTS proteins controlled by PTS-dependent phosphorylation

Proteins closely related to the PTS

  • Crh: HPr-like protein with exculsively regulatory functions (His-15 is not conserved
  • HprK: HPr-kinase, key factor for carbon catabolite repression
