Abstract
Histidine (His) is widely involved in the structure and function of biomolecules. Transition-metal ions, such as Zn2+ and Cu2+, widely exist in biological environments, and they are crucial to many life-sustaining physiological processes. Herein, by employing density function calculations, we theoretically show that the water affinity of His can be enhanced by the strong cation–π interaction between His and Zn2+ and Cu2+. Further, the solubility of His is experimentally demonstrated to be greatly enhanced in ZnCl2 and CuCl2 solutions. The existence of cation–π interaction is demonstrated by fluorescence, ultraviolet (UV) spectroscopy and nuclear magnetic resonance (NMR) experiments. These findings are of great importance for the bioavailability of aromatic drugs and provide new insight for understanding the physiological functions of transition metal ions.

Abstract
Zinc (Zn) is an essential micro-nutrient for humans, and Zn deficiency is of global concern. In addition to inherited and pathological Zn deficiencies, insufficient dietary intake is leading cause, especially in those consuming cereal grains as a stable food, in which Zn concentration and bioavailability are relatively low. To improve Zn levels in the human body, it is important to understand the accumulation and bioavailability of Zn in cereal grains. In recent years, knowledge on the molecular mechanisms underlying Zn uptake, transport, homeostasis, and deposition within cereal crops has been accumulating, paving the way for a more targeted approach to improving the nutrient status of crop plants. In this paper, we briefly review existing studies on the distribution and transport pathways of Zn in major small-grained cereals, using wheat as a case study. The findings confirm that Zn transport in plants is a complex physiological process mainly governed by Zn transporters and metal chelators. This work reviews studies on Zn uptake, transport, and deposition in wheat plants, summarizes the possible barriers impairing Zn deposition in wheat grains, and describes strategies for increasing Zn concentration in wheat grains.

J Sep Sci 2019; 42:3631-3639. [PMID: 31651081 DOI: 10.1002/jssc.201900908] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2019] [Revised: 10/04/2019] [Accepted: 10/04/2019] [Indexed: 11/06/2022]
Abstract
The interactive behavior of an amphipathic peptide with the Cu2+ , Ni2+ , and Zn2+ complexes of 1,4-bis(triazacyclonon-1-yl)butane), bis(tacn)but , immobilized onto Sepharose CL-4B, has been investigated. The effects of incubation time, as well as the incubation buffer pH and ionic strength, have been examined. The binding data have been interrogated using Langmuir, Langmuir-Freundlich, bi-Langmuir, and Temkin isothermal models and Scatchard plots. These results confirm that this amphipathic peptide binds with relatively high capacities to the immobilized Cu2+ - and Ni2+ -1,4-bis(triazacyclonon-1-yl)butane)-Sepharose CL-4B sorbents via at least two discrete sites. However, the corresponding immobilized Zn2+ -sorbent had low binding capacity. Moreover, the magnitude of the binding capacities of these sorbents was dependent on the pH and ionic strength of the incubation buffer. These results are relevant to the isolation of E. coli expressed recombinant proteins that incorporate this and related amphipathic peptide tags, containing two or more histidine residues, located at the N- or C-terminus of the recombinant protein, and the co-purification of low abundance host cell proteins of diverse structure, by immobilized metal ion affinity chromatographic methods.

Abstract
The coordination chemistry of 2,6-bis(1,4,7-triazacyclonon-1-ylmethyl)pyridine (Lpyx, 1) has been investigated and shown to yield bi-nuclear metal complexes in the presence of zinc(ii), copper(ii), or nickel(ii) ions. The reaction of (Lpyx)·7HCl (2) with Zn(NO3)2 gave the monomeric [Zn2(μ-Cl)2(Lpyx)(H2O)](ClO4)2 (3) in which the ligand encapsulates a Zn2(μ-Cl)2 moiety. Similar treatment of 2 with Cu(NO3)2 gave a bi-nuclear complex cation which exists as a 1 : 1 co-crystal {[Cu(Cl)(Lpyx)Cu(μ-Cl)(Cl)](BF4)(H2O)}2 and {[Cu(Cl)(Lpyx)Cu(μ-Cl)(H2O)](BF4)2(H2O)}2 (4) with two discrete CuII centres bridged by the Lpyx ligand and dimerised through an unsymmetrical Cu2(μ-Cl)2 interaction. Similarly, reaction of 2 with Ni(NO3)2 also gave a dimeric complex {[Ni(Cl)(μ-Cl)(Lpyx)Ni(NO3)(H2O)](PF6)}2 (5) containing two discrete NiII centres with dimerisation occurring through a symmetrical Ni2(μ-Cl)2 interaction. In all cases, the Lpyx ligand binding is unsymmetrical between the two metal centres being tridentate to one and tetradentate to the other through an additional coordination of the pyridyl linker.

Abstract
These investigations were designed to improve capture efficiency and selectivity in the immobilized metal ion affinity chromatographic (IMAC) purification of tagged recombinant proteins expressed in Escherichia coli cells, utilizing an alternative and novel class of immobilized metal binding ligands. The impact of loading conditions and lysate composition on the IMAC purification of NT1A- or His6 -tagged green fluorescent protein (GFP), using the ligands 1,4,7-triazacyclononane (tacn) and bis(1,4,7-triazacyclononyl)propane (dtnp), charged with Cu(2+) ions, has thus been explored. These findings were compared to the performance of a commercial adsorbent, IMAC Sepharose™ 6 FF, similarly charged with Cu(2+) ions. With the same loading, wash and elution protocols, the tacn- and dtnp-derived adsorbents showed higher selectivity in terms of removal of E. coli host cell proteins than the commercial adsorbent, while low molecular weight components in the crude lysate had a higher impact on the binding capacities of tacn- and dtnp-derived adsorbents. This effect of lysate composition could be reduced through osmotic shock treatment of the E. coli cells prior to lysis. Additionally, the protein-binding capacities of the tacn-based resins were enhanced by increasing their ligand densities. Because both the tacn- and the dtnp-derived IMAC adsorbents exhibit very high metal ion stability constants, under the chromatographic conditions examined, they could be used several times without re-charging with Cu(2+) ions. The results of these studies thus expand the general application scope of tacn-based IMAC resins for use in the capture and purification of tagged recombinant proteins.

Abstract
This study describes the determination of the adsorption isotherms and binding kinetics of tagged recombinant proteins using a recently developed IMAC cassette system and employing automated robotic liquid handling procedures for IMAC resin screening. These results confirm that these new IMAC resins, generated from a variety of different metal-charged binuclear 1,4,7-triaza-cyclononane (tacn) ligands, interact with recombinant proteins containing a novel N-terminal metal binding tag, NT1A, with static binding capacities similar to those obtained with conventional hexa-His tagged proteins, but with significantly increased association constants. In addition, higher kinetic binding rates were observed with these new IMAC systems, an attribute that can be positively exploited to increase process productivity. The results from this investigation demonstrate that enhancements in binding capacities and affinities were achieved with these new IMAC resins and chosen NT1A tagged protein. Further, differences in the binding performances of the bis(tacn) xylenyl-bridged ligands were consistent with the distance between the metal binding centres of the two tacn moieties, the flexibility of the ligand and the potential contribution from the aromatic ring of the xylenyl group to undergo π/π stacking interactions with the tagged proteins.
