ENZYME entry: EC

Accepted Name
Phosphohistidine phosphatase.
Alternative Name(s)
Protein histidine phosphatase.
Reaction catalysed
A [protein]-N-phospho-L-histidine + H(2)O <=> a [protein]-L-histidine + phosphate
  • This eukaryotic enzyme dephosphorylates phosphorylated histidine residues within proteins and peptides.
  • The enzyme acts on phosphate groups attached to both the pros- and tele-nitrogen atoms, but the pros- position is somewhat preferred (by a factor of two at the most).
  • The substrate specificity depends on the amino acid sequence or structural context of the phosphohistidine in a phosphoprotein.
  • The enzyme is also active on free phosphoramidate and peptide-bound phospholysine.
