The imidazole sidechain of the histidine residue commonly serves as a ligand in metalloproteins. One example is the axial base attached to Fe in myoglobin and hemoglobin. Poly-histidine tags (of six or more consecutive H residues) are utilized for protein purification by binding to columns with nickel or … See more Histidine (symbol His or H) is an essential amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated –NH3 form under biological conditions), a carboxylic acid group … See more The conjugate acid (protonated form) of the imidazole side chain in histidine has a pKa of approximately 6.0. Thus, below a pH of 6, the imidazole ring is mostly protonated (as described by the Henderson–Hasselbalch equation).

WebApr 11, 2024 · Inorganic polyphosphate (polyP) is a linear polymer of orthophosphate that is present in nearly all organisms studied to date. A remarkable function of polyP involves its attachment to lysine residues via non-enzymatic post-translational modification (PTM) that is presumed to be covalent. Here, we show that proteins containing tracts of consecutive … WebWe typically insert 10 residue histidine tags (His 10) into target proteins to act as Cy3/5NTA-binding sites.
