[protein]-N-phospho-L-histidine phosphohydrolase
a [protein]-N-phospho-L-histidine + H2O = a [protein]-L-histidine + phosphate [RN:R11258 R11259]

[protein]-N-pros-phospho-L-histidine [CPD:C04261];
[protein]-N-tele-phospho-L-histidine [CPD:C04262];

[protein]-L-histidine [CPD:C00615];
phosphate [CPD:C00009]
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) [4]. 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 [1,4] and peptide-bound phospholysine [5].
