Chains	Enzyme Name	Description	Catalytic Residues
A	phosphohistidine phosphatase M-CSA #952	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) [PMID:19836471]. 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 [PMID:12383260, PMID:19836471] and peptide-bound phospholysine [PMID:25574816].
