Abstract
Superoxide dismutase (SOD) is a class of enzymes that restrict the biological oxidant cluster enzyme system in the body, which can effectively respond to cellular oxidative stress, lipid metabolism, inflammation, and oxidation. Published studies have shown that SOD enzymes (SODs) could maintain a dynamic balance between the production and scavenging of biological oxidants in the body and prevent the toxic effects of free radicals, and have been shown to be effective in anti-tumor, anti-radiation, and anti-aging studies. This research summarizes the types, biological functions, and regulatory mechanisms of SODs, as well as their applications in medicine, food production, and cosmetic production. SODs have proven to be a useful tool in fighting disease, and mimetics and conjugates that report SODs have been developed successively to improve the effectiveness of SODs. There are still obstacles to solving the membrane permeability of SODs and the persistence of enzyme action, which is still a hot spot and difficulty in mining the effect of SODs and promoting their application in the future.

Shah JS, Buckmeier BG, Griffith W, Olafson PU, Perez de Leon AA, Renthal R. Odorant-binding protein from the stable fly (Stomoxys calcitrans) has a high-histidine N-terminal extension that binds transition metals. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2022; 141:103707. [PMID: 34979251 DOI: 10.1016/j.ibmb.2021.103707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Revised: 12/19/2021] [Accepted: 12/26/2021] [Indexed: 06/14/2023]
Abstract
The role of odorant- and pheromone-binding proteins (OBPs) in olfactory function is not fully understood. We found an OBP sequence from the stable fly, Stomoxys calcitrans, ScalOBP60, that has a 25 amino acid N-terminal extension with a high content of histidine and acidic amino acids, suggesting a possible metal binding activity. A search of public databases revealed a large number of other fly OBPs with histidine-rich N-terminal extensions, as well as beetle, wasp and ant OBPs with histidine-rich C-terminal extensions. We recombinantly expressed ScalOBP60, as well as a truncated sequence which lacks the histidine-rich N-terminal region, tScalOBP60. Using fluorescence quenching and electrospray quadrupole time-of-flight mass spectrometry (ESI-QTOF), we detected two different types of metal-binding sites. Divalent copper, nickel and zinc bind to the N-terminal histidine-rich region, and divalent copper binds to an internal sequence position. Comparison of the ESI-QTOF spectra of ScalOBP60 and tScalOBP60 showed that the histidine-rich sequence is structurally disordered, but it becomes more ordered in the presence of divalent metal. When copper is bound to the internal site, binding of a hydrophobic ligand to ScalOBP60 is inhibited. The internal and N-terminal metal sites interact allosterically, possibly through a conformational equilibrium, suggesting a mechanism for metal regulation of ligand binding to ScalOBP60. Based on our studies of ScalOBP60, we propose several possible olfactory and non-olfactory functions for this OBP.

Abstract
Antimicrobial peptides are a promising group of compounds used for the treatment of infections. In some cases, metal ions are essential to activate these molecules. Examples of metalloantibiotics are, for instance, bleomycin and dermcidin. This study is focused on three new pseudopeptides with potential biological activity. The coordination behavior of all ligands with Cu(II) and Ni(II) ions has been examined. Various analytical methods such as potentiometric titration, UV-Vis and CD spectroscopies, and mass spectrometry were used. All compounds are convenient chelators for metal ion-binding. Two of the ligands tested have histidine residues. Surprisingly, imidazole nitrogen is not involved in the coordination of the metal ion. The N-terminal amino group, Dab side chains, and amide nitrogen atoms of the peptide bonds coordinated Cu(II) and Ni(II) in all the complexes formed. The cytotoxicity of three pseudopeptides and their complexes was evaluated. Moreover, their other model allowed for assessing the attenuation of LPS-induced cytotoxicity and anti-inflammatory activities were also evaluated, the results of which revealed to be very promising.

Abstract
The effect of the chelation process on the pH-dependent stability of organic trace minerals (OTMs) used as mineral supplements in animal nutrition was assessed using analytical techniques such as potentiometry, Fourier Transform Infrared Spectroscopy (FTIRS) and amino acid profiling. The aim was to understand the influence and relative importance of the manufacturing conditions on mineral chelation and the subsequent pH stability of OTMs. A selection of OTMs were assessed over a wide pH range to account for the typical environmental changes encountered in the gastrointestinal (GI) tract. In the case of proteinate type products, the potentiometric assessment of free mineral concentration indicated that the hydrolysis procedure used to generate the chelating peptides was the major influencer of the pH stability of the products. Many products are available under the umbrella term "OTMs", including amino acid complexes, amino acid chelates, polysaccharide complexes and proteinates. Significant differences in the pH-dependent stability of a range of commercially available OTMs were observed.

Abstract
The role of the pentapeptide, NHSFM, derived from the surface exposed part of the metal ion binding loop of the subunit II of cytochrome c oxidase on the maturation of the binuclear purple CuA center of the enzyme has been investigated using several experimental and computational methods. The copper ion was found to form 1:1 complex of the pentapeptide with a binding constant ~ 104 M-1 to 105 M-1, where a 4 ligand coordination from the peptide in a type 2 copper center was revealed. The pH dependence of the metal-peptide was associated with a [Formula: see text] of ~ 10 suggesting deprotonation of the N-terminal amine. EXAFS studies as well as DFT calculations of the metal-peptide complexes revealed pH dependent changes in the metal-ligand bond distances. Spectroscopic properties of the metal peptides calculated from TDDFT studies agreed with the experimental results. Restrained molecular dynamics (RMD) simulations indicated coordination of a carbonyl oxygen from the asparagine (N) side chain and of water molecules apart from histidine (H), methionine (M) and terminal amine of asparagine (N) in a distorted square planar geometry of Cu-NHSFM. Analyses of the backbone distances as well as B-factors for the metal peptide suggested that the peptide backbone becomes more compact and rigid on binding of the metal ion. This indicated that binding of copper ion to this pentapeptide in the protein possibly cause movement of the protein backbone bringing other coordinating residues closer to the copper ion, and thus helping in sequential uptake of copper ions to the protein.

Abstract
Divalent metal ions are essential nutrients for all living organisms and are commonly protein-bound where they perform important roles in protein structure and function. This regulatory control from metals is observed in the relatively abundant plasma protein histidine-rich glycoprotein (HRG), which displays preferential binding to the second most abundant transition element in human systems, Zinc (Zn2+). HRG has been proposed to interact with a large number of protein ligands and has been implicated in the regulation of various physiological and pathological processes including the formation of immune complexes, apoptotic/necrotic and pathogen clearance, cell adhesion, antimicrobial activity, angiogenesis, coagulation and fibrinolysis. Interestingly, these processes are often associated with sites of tissue injury or tumour growth, where the concentration and distribution of Zn2+ is known to vary. Changes in Zn2+ levels have been shown to modify HRG function by altering its affinity for certain ligands and/or providing protection against proteolytic disassembly by serine proteases. This review focuses on the molecular interplay between HRG and Zn2+, and how Zn2+ binding modifies HRG-ligand interactions to regulate function in different settings of tissue injury.

Abstract
The basic knowledge about biological inorganic chemistry, thermodynamics and metal binding sites of metalloproteins is crucial for the understanding of their metal binding-structure-function relationship. Metal-peptide complexes are useful and commonly used models of metal-enzyme active sites, among which copper and zinc models are one of the most extensively studied. HENRYK is a peptide sequence present in numerous proteins, and serves as a potentially tempting binding site for Cu2+ and Zn2+. Maybe more importantly, HENRYK also happens to be the first name of our group leader. The results of this work, which, at the first glance, might seem to be a 'chemical scrabble', went far beyond our expectations and surprised us with a novel, uncommon behavior of a Cu2+ complex with a peptide with a histidine in position one. At low pH, the binding is a typical histamine-like coordination, but with the increase of pH, the imidazole nitrogen is moved to the axial position and replaced with an amide; at basic pH, the binding mode is a {NH2, 3N-} one in the equatorial plane. It is important to note, that no dimeric species are formed in between. Such binding is thermodynamically much more stable than a simple complex with histamine, and quite comparable to complexes with several possible imidazole anchoring sites.

Abstract
The brain specific zinc transporter protein ZnT3 can be related to the amyloid neuropathology of Alzheimer's disease. In order to analyze the metal binding ability of human ZnT3 protein, here we report a potentiometric and solution structural (UV-Vis, CD, EPR, NMR) study of nickel(II), copper(II) and zinc(II) complexes of three peptides mimicking the possible metal binding sequences of this protein. The peptide L¹ (Ac-RHQAGPPHSHR-NH2) is a minimalist, the cyclic peptide L² (cyclo(Ac-CKLHQAGPPHSHGSRGAEYAPLEEGPEEKC-NH2) is a more complete model of the intracellular His-rich loop, which is widely accepted as a putative metal binding site. The peptide L³ (Ac-PFHHCHRD-NH2) is the model of the conserved cytoplasmic N-terminal -HHCH- sequence. In the physiological pH-range, the ZnL¹, ZnH3L² and ZnL³ complexes are the major species in the corresponding binary systems, with {3N(im)}, {3N(im),2/3O(amide)} and {3N(im),S(-)} coordination environments, respectively. The species ZnL³ has 3-4 orders of magnitude higher stability than the other two complexes, indicating the presence of a high-affinity zinc-binding site at the N-terminal tail of the human ZnT3 transporter. Moreover, L³ shows preferred zinc binding as compared to nickel (log β(ZnL³) - log β(NiL³) = 2.3), probably due to the higher preference of zinc(II) for tetrahedral geometry. These facts suggest that zinc binding to the N-terminal -HHCH- sequence of human ZnT3 may be involved in the biological activity of this zinc transporter protein in zinc sensing, binding or translocation processes.

The copper(II) and zinc(II) coordination mode of HExxH and HxxEH motif in small peptides: the role of carboxylate location and hydrogen bonding network. J Inorg Biochem 2013; 130:92-102.

Abstract
Copper(II) and zinc(II) complexes with two hexapeptides encompassing HExxH and HxxEH motif were characterized by means of a combined experimental and theoretical approach. Parallel tempering and density functional theory (DFT) investigations show the presence of different hydrogen bonding networks between the copper(II) and zinc(II) complexes with the two peptides, suggesting a significant contribution of these non-covalent interactions to the stability constant values. The glutamate carboxylate group has a direct role in metal ion binding. The location of this amino acid along the sequence of the investigated peptides is critical to determine thermodynamic and spectroscopic features of the copper(II) complex species, whereas is less relevant in the zinc(II) complexes formation. Electrospray ionization mass spectrometry (ESI-MS) characterization of the zinc(II) complex species show that in the [ZnH-2L] two deprotonated amide nitrogen atoms are involved in the metal coordination environment, an uncommon behavior in zinc(II) complexes for multi-histidine ligands.

Abstract
Speciation of the complexes of zinc(II) with a dodecapeptide (Ac-SCPGDQGSDCSI-NH2), inspired by the metal binding domain of MerR metalloregulatory proteins, have been studied by pH-potentiometric titrations, UV, SRCD (synchrotron radiation circular dichroism) and (1)H NMR experiments. (MerR is a family of transcriptional regulators the archetype of which is the Hg(2+)-responsive transcriptional repressor-activator MerR protein.) The aim of the ligand-design was to retain the advantageous metal binding features of MerR proteins in a model peptide for the efficient capture of toxic metal ions. The peptide binds zinc(II) via two deprotonated Cys-thiol groups and one of the Asp-carboxylates in the ZnL parent complex, possessing a remarkably high stability (logK=9.93). In spite of the relatively long peptide loop, bis-complexes are also formed with the metal ion under basic conditions. In a competition with cadmium(II) or mercury(II), zinc(II) cannot prevent the binding of toxic metal ions by the thiolate donor groups of the ligand. Around neutral pH one equivalent of mercury(II) was shown to fully replace zinc(II) from the ZnL species. Partial replacement of zinc(II) from the peptide by one equivalent of cadmium(II), relative to zinc(II) and the ligand, is also presumable, nevertheless, spectroscopic data may suggest the formation of mixed metal ion complexes, as well. Based on the obtained results the investigated dodecapeptide can be a promising candidate for capturing toxic metal ions in practical applications.

Abstract
In order to mimic the active center of matrix metalloproteinases (MMPs), we synthesized a pentadecapeptide (Ac-KAHEFGHSLGLDHSK-NH2) corresponding to the catalytic zinc(II) binding site of human MMP-13. The multi-domain structural organization of MMPs fundamentally determines their metal binding affinity, catalytic activity and selectivity. Our potentiometric, UV-visible, CD, EPR, NMR, mass spectrometric and kinetic studies are aimed to explore the usefulness of such flexible peptides to mimic the more rigid metal binding sites of proteins, to examine the intrinsic metal binding properties of this naked sequence, as well as to contribute to the development of a minimalist, peptide-based chemical model of MMPs, including the catalytic properties. Since the multiimidazole environment is also characteristic for copper(II), and recently copper(II) containing variants of MMPs have been identified, we also studied the copper(II) complexes of the above peptide. Around pH 6-7 the peptide, similarly to MMPs, offers a {3Nim} coordination binding site for both zinc(II) and copper(II). In the case of copper(II), the formation of amide coordinated species at higher pH abolished the analogy with the copper(II) containing MMP variant. On the other hand, the zinc(II)-peptide system mimics some basic features of the MMP active sites: the main species around pH7 (ZnH2L) possesses a {3Nim,H2O} coordination environment, the deprotonation of the zinc-bound water takes place near the physiological pH, it forms relatively stable ternary complexes with hydroxamic acids, and the species ZnH2L(OH) and ZnH2L(OH)2 have notable hydrolytic activity between pH7 and 9.

Abstract
Two decapeptides containing three His and two Pro-Gly β-turn inducer units (C-Asn, cyclic) and three His and a single Pro-Gly unit (O-Asn, open) have been synthesized. A detailed potentiometric study showed that while O-Asn binds up to 3 equiv. of Cu(2+) ions, C-Asn only coordinates two before precipitation occurred. Nonetheless, at a 1 : 1 Cu(2+)/peptide ratio both peptides form a major [CuHL](3+) species and spectroscopic studies (UV-Vis, CD and EPR) revealed a very similar copper(ii) complex where the metal ion is coordinated solely by the imidazole rings of the His residues adopting a square planar or square pyramidal geometry. The corrected stability constants of the protonated species (log K(CuH(O-Asn)) = 8.17 and log K(CuH(C-Asn)) = 9.11) indicate that the cyclic peptide binds Cu(2+) with higher affinity and this value represents the highest value reported so far for this type of coordination. Additionally, the calculated value of the effective stability constant, K(eff), showed that C-Asn has a higher affinity for Cu(2+) at all pH values not only at a 1 : 1 ratio but even at a 2 : 1 ratio. The replacement of the asparagine residue by an aspartic amino acid increases the Cu(2+) affinity of the aspartic counterparts, C-Asp and O-Asp, which at a 1 : 1 Cu(2+)/peptide ratio also form a major species, [CuHL](2+) in these cases, with Cu(2+) coordinated to the three histidine residues and one aspartic residue. These data show how cyclization and coordination to the aspartic residue increase the binding strength and preclude the coordination of the amide nitrogen up to higher pH values, stabilizing therefore, the species where Cu(2+) is solely coordinated by the side chain functionalities.

Abstract
In this paper we present the formation of mono- and binuclear complexes by the octapeptide (c(HKHPHKHP)) with copper(II) ions. The ligand was synthesized manually by the solid-phase method. Its characteristic cyclic structure significantly influences the coordination abilities. The studied peptide has two Pro amino acid residues in the sequence. This causes the formation of two independent centres able to undertake metal ion binding. The potentiometric and spectroscopic (UV-vis, CD and EPR) studies were carried out in aqueous solutions in the pH range 2.5-11.0 at 298 K, HNO(3) was used as the solvent with KNO(3), where the ionic strength was 0.1 M. The analysis of the potentiometric together with spectroscopic studies have shown that the investigated peptide forms only mono-nuclear complexes when the metal-to-ligand molar ratio is 1 : 1. When the concentration of Cu(ii) ions increases and the ligand-to-metal molar ratio is 1 : 2 the formation of binuclear complexes is preferred in the system.

Abstract
Designing small peptides that are capable of binding Cu(2+) ions mainly through the side-chain functionalities is a hard task because the amide nitrogen atoms strongly compete for Cu(2+) ion coordination. However, the design of such peptides is important for obtaining biomimetic small systems of metalloenyzmes as well as for the development of artificial systems. With this in mind, a cyclic decapeptide, C-Asp, which contained three His residues and one Asp residue, and its linear derivative, O-Asp, were synthesized. The C-Asp peptide has two Pro-Gly β-turn-inducer units and, as a result of cyclization, and as shown by CD spectroscopy, its backbone is constrained into a more defined conformation than O-Asp, which is linear and contains a single Pro-Gly unit. A detailed potentiometric, mass spectrometric, and spectroscopic study (UV/Vis, CD, and EPR spectroscopy) showed that at a 1:1 Cu(2+)/peptide ratio, both peptides formed a major [CuHL](2+) species in the pH range 5.0-7.5 (C-Asp) and 5.5-7.0 (O-Asp). The corrected stability constants of the protonated species (log K*(CuH(O-Asp))=9.28 and log K*(CuH(C-Asp))=10.79) indicate that the cyclic peptide binds Cu(2+) ions with higher affinity. In addition, the calculated value of K(eff) shows that this higher affinity for Cu(2+) ions prevails at all pH values, not only for a 1:1 ratio but even for a 2:1 ratio. The spectroscopic data of both [CuHL](2+) species are consistent with the exclusive coordination of Cu(2+) ions by the side-chain functionalities of the three His residues and the Asp residue in a square-planar or square-pyramidal geometry. Nonetheless, although these data show that, upon metal coordination, both peptides adopt a similar fold, the larger conformational constraints that are present in the cyclic scaffold results in different behaviour for both [CuHL](2+) species. CD and NMR analysis revealed the formation of a more rigid structure and a slower Cu(2+)-exchange rate for [CuH(C-Asp)](2+) compared to [CuH(O-Asp](2+). This detailed comparative study shows that cyclization has a remarkable effect on the Cu(2+)-coordination properties of the C-Asp peptide, which binds Cu(2+) ions with higher affinity at all pH values, stabilizes the [CuHL](2+) species in a wider pH range, and has a slower Cu(2+)-exchange rate compared to O-Asp.

Abstract
Cobalt is an essential trace element in both prokaryotes and eukaryotes. Nevertheless, it occurs less frequently in metalloproteins than other transition metals. This low occurrence appears to be due to the metal's low abundance in nature as well as its competition with iron, whose biologically critical functions include respiration and photosynthesis. In this review, we discuss the biological role of cobalt, the major effects of cobalt on iron utilization, as well as several mechanisms that cells have developed to circumvent the toxicity of cobalt while still exploiting its chemistry.

Abstract
The homeostasis of metal ions, especially copper and zinc, is a major factor that may influence the prion diseases and the biological function of prion protein (PrP). The His-rich regions are basic sites for metal binding and antioxidant activity of the PrP structures. Animal prion-like proteins contain also His-rich domains, and their coordination chemistry may provide better insight into the chemistry and biology of PrP structures and related diseases. Herein, we report an equilibrium study on heteronuclear Zn(2+)-Cu(2+) complexes with zrel-PrP fragments from zebrafish. Potentiometric, spectroscopic, and mass spectrometric methods showed that the binding of copper is much more effective than the binding of zinc. At physiological pH, both metals bind to the histidine imidazole N donors of the studied peptides.
