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.

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
- GlpK: phosphorylated by HPr
- GlcT: phosphorylated by HPr and by PtsG
- LicT: phosphorylated by HPr and likely by BglP
- SacT: phosphorylated by HPr and likely by SacP

- ManR: phosphorylated by HPr and likely by ManP
- MtlR: phosphorylated by HPr and likely by MtlA
- Protein kinases of two-component systems
These kinases are dimeric proteins. Phosphorylation occurs from one subunit to the other (not quite an autophosphorylation).
- Crh: HPr-like protein with exculsively regulatory functions (His-15 is not conserved
- HprK: HPr-kinase, key factor for carbon catabolite repression
