Histidine-rich metal-binding protein

So called for emphatize its origins in Helicobacter pylori and its avidity for nickel. Consisting of 60 aminoacids, the protein is rich in histidine (28 residues, 46.7 %) and contains short repeating motifs, it exists as an equilibration of multimeric forms in solution, with 20-mers (approx. 136 kDa) being the predominant species. Hpn can bind tightly and reversibly up to five Ni2+ ions per each monomer of 7 kDa in a pH-dependent manner (pH 7.4 ). In H. pylori play an important role in storing nickel required to the survival of the bacterium.
