WebbNickel generally provides good binding efficiency to His-tagged proteins but also tends to bind nonspecifically to endogenous proteins that contain histidine clusters. As … WebbIn Rhodospirillum rubrum, three nickel-dependent proteins, CooC, CooT and CooJ are required for Ni insertion into the active site. Among them, CooJ is a histidine-rich protein, containing two distinct and spatially separated Ni(II)-binding sites: a strictly conserved N-terminal site and a variable histidine tail at the C-terminus.

WebbThe recombinant Hpnl exists as an oligomer in the native state and binds to two molar equivalents of nickel ions per monomer with a dissociation constant of 3.8 μM, and may serve a role in binding/storage or detoxification of excess nickel ions. Hpn-like (Hpnl) protein, encoded by the hpnl gene in Helicobacter pylori and featuring a histidine-rich … tsp1 form south africaGenerally, for this sort of a technique, histidine binding is titrated using pH instead of imidazole binding—at a high pH, histidine binds to nickel or cobalt, but at low pH (~6 for cobalt and ~4 for nickel), histidine becomes protonated and is competed off of the metal ion. Visa mer A polyhistidine-tag is an amino acid motif in proteins that typically consists of at least six histidine (His) residues, often at the N- or C-terminus of the protein. It is also known as hexa histidine-tag, 6xHis-tag, His6 tag, by the US … Visa mer In general, proteins possess more or less the ability to coordinate metal ions on their surface, and it is possible to separate proteins by chromatography making use of the difference in … Visa mer The most common polyhistidine tags are formed of six histidine (6xHis tag) residues - which are added at the N-terminus preceded by Visa mer The polyhistidine-tag can be successfully used for the immobilization of proteins on a surface such as on a nickel- or cobalt-coated microtiter plate or on a protein array. Visa mer Protein purification Polyhistidine-tags are often used for affinity purification of polyhistidine-tagged recombinant … Visa mer The polyhistidine-tag can also be used to detect the protein via anti-polyhistidine-tag antibodies or alternatively by in-gel staining (SDS-PAGE) with fluorescent probes bearing metal ions. … Visa mer HQ tag The HQ tag has alternating histidine and glutamine (HQHQHQ).
