Bioinorganic motifs: towards functional classification of metalloproteins. (1/15)

The habitat of bioinorganic motifs (BIMs) is at the interface of biological inorganic chemistry and bioinformatics. BIM is defined as a common structural feature shared by functionally related, but not necessarily homologous, proteins, and consisting of the metal atom(s) and first coordination shell ligands. BIMs appear to be suitable for classification of metal centres at any level, from groups of unrelated proteins with similar function to different functional states of the same protein, and for description of possible evolutionary relationships of metalloproteins. However, they have not attracted wide attention from the bioinformatics community. Although their presence is appreciated, they are difficult to predict-therefore the current 'high-throughput' initiatives are likely to miss or ignore them altogether. The protein sequence databases do not distinguish between proteins containing different prosthetic groups (unless they have different sequences) or between apo- and holoprotein. On the other hand, the protein structure databases include data on 'hetero compounds' of various origin but these data are often inconsistent. A number of specialized databases dealing with BIMs and attempts to classify them are reviewed.

Effect of pressure on electron transfer reactions in inorganic and bioinorganic chemistry. (2/15)

Kinetic and thermodynamic studies involving the application of different high-pressure techniques, are very useful in gaining mechanistic information on the basis of volume changes that occur during inorganic and bioinorganic electron transfer reactions. The most fundamental type of electron transfer reaction concerns self-exchange reactions, for which the overall reaction volume is zero, and activation volumes can be measured and discussed. In the case of non-symmetrical electron transfer reactions, intra- and intermolecular processes can be studied and volume profiles can be constructed. Precursor complex formation can in some cases be recognized kinetically in such systems. Typical values of activation and reaction volumes are reviewed for various reversible and irreversible electron transfer reactions. Mechanistic conclusions reached on the basis of these parameters are presented. Volume profiles for electron transfer reactions enable a simplistic presentation of the reaction mechanism on the basis of intrinsic and solvational volume changes along the reaction coordinate.  (+info)

Electron-nuclear double resonance spectroscopy (and electron spin-echo envelope modulation spectroscopy) in bioinorganic chemistry. (3/15)

This perspective discusses the ways that advanced paramagnetic resonance techniques, namely electron-nuclear double resonance (ENDOR) and electron spin-echo envelope modulation (ESEEM) spectroscopies, can help us understand how metal ions function in biological systems.  (+info)

Bioinorganic chemistry in the postgenomic era. (4/15)

Genome sequencing has revolutionized all fields of life sciences. Bioinorganic chemistry is certainly not immune to this influence, which is presenting unprecedented challenges. A new goal for bioinorganic chemistry is the investigation of the linkages between inorganic elements and genomic information. This requires new advancements andor the development of new expertise in fields such as bioinformatics and genetics but also provides a driving force to push forward the exploitation of traditional analytical techniques and spectroscopic tools. The "case study" of metal homeostasis in cells is discussed to provide a flavor of the current evolution of the field.  (+info)

The bioinorganic chemistry of iron in oxygenases and supramolecular assemblies. (5/15)

The bioinorganic chemistry of iron is central to life processes. Organisms must recruit iron from their environment, control iron storage and trafficking within cells, assemble the complex, iron-containing redox cofactors of metalloproteins, and manage a myriad of biochemical transformations by those enzymes. The coordination chemistry and the variable oxidation states of iron provide the essential mechanistic machinery of this metabolism. Our current understanding of several aspects of the chemistry of iron in biology are discussed with an emphasis on the oxygen activation and transfer reactions mediated by heme and nonheme iron proteins and the interactions of amphiphilic iron siderophores with lipid membranes.  (+info)

Biological inorganic chemistry at the beginning of the 21st century. (6/15)

Advances in bioinorganic chemistry since the 1970s have been driven by three factors: rapid determination of high-resolution structures of proteins and other biomolecules, utilization of powerful spectroscopic tools for studies of both structures and dynamics, and the widespread use of macromolecular engineering to create new biologically relevant structures. Today, very large molecules can be manipulated at will, with the result that certain proteins and nucleic acids themselves have become versatile model systems for elucidating biological function.  (+info)

Sub-micrometer anatomical models of the sarcolemma of cardiac myocytes based on confocal imaging. (7/15)

We describe an approach to develop anatomical models of cardiac cells. The approach is based on confocal imaging of living ventricular myocytes with submicrometer resolution, digital image processing of three-dimensional stacks with high data volume, and generation of dense triangular surface meshes representing the sarcolemma including the transverse tubular system. The image processing includes methods for deconvolution, filtering and segmentation. We introduce and visualize models of the sarcolemma of whole ventricular myocytes and single transversal tubules. These models can be applied for computational studies of cell and sub-cellular physical behavior and physiology, in particular cell signaling. Furthermore, the approach is applicable for studying effects of cardiac development, aging and diseases, which are associated with changes of cell anatomy and protein distributions.  (+info)

Aerobic life make extensive use of metals such as iron, copper, and manganese. Heme is utilized by red blood cells in the form of hemoglobin for oxygen transport and is perhaps the most recognized metal system in biology. Other oxygen transport systems include myoglobin, hemocyanin, and hemerythrin. Oxidases and oxygenases are metal systems found throughout nature that take advantage of oxygen to carry out important reactions such as energy generation in cytochrome c oxidase or small molecule oxidation in cytochrome P450 oxidases or methane monooxygenase. Some metalloproteins are designed to protect a biological system from the potentially harmful effects of oxygen and other reactive oxygen-containing molecules such as hydrogen peroxide. These systems include peroxidases, catalases, and superoxide dismutases. A complementary metalloprotein to those that react with oxygen is the oxygen evolving complex present in plants. This system is part of the complex protein machinery that produces oxygen as ...

Bioorganic chemistry is a rapidly growing scientific discipline that combines organic chemistry and biochemistry. While biochemistry aims at understanding biological processes using chemistry, bioorganic chemistry attempts to expand organic-chemical researches (that is, structures, synthesis, and kinetics) toward biology. When investigating metalloenzymes and cofactors, bioorganic chemistry overlaps bioinorganic chemistry. Biophysical organic chemistry is a term used when attempting to describe intimate details of molecular recognition by bioorganic chemistry. Bioorganic chemistry is that branch of life science that deals with the study of biological processes using chemical methods. Nelson J.

Dr. Christopher Exley- The Systemic Toxicity of Aluminium Adjuvants. Dr. Christopher Exley is the Reader in Bioinorganic Chemistry at The Birchall Centre, Keele University in Staffordshire and Honorary Professor at the UHI Millennium Institute. Exley is a biologist (University of Stirling) with a PhD in the ecotoxicology of aluminium (University of Stirling). His research career (1984-present) has focused upon an intriguing paradox; 'how the third most abundant element of the Earth's crust (aluminium) is non-essential and largely inimical to life'. Investigating this mystery has required research in myriad fields from the basic inorganic chemistry of the reaction of aluminium and silicon to the potentially complex biological availability of aluminium in humans. Exley is also fascinated by the element silicon in relation to living things which, as the second most abundant element of the Earth's crust, is also almost devoid of biological function. One possible function of silicon is

Redox-inactive metal ions that function as Lewis acids play pivotal roles in modulating the reactivity of oxygen-containing metal complexes and metalloenzymes, such as the oxygen-evolving complex in photosystem II and its small-molecule mimics. Here we report the synthesis and characterization of non-haem iron(III)-peroxo complexes that bind redox-inactive metal ions, (TMC)FeIII-(μ,η 2:η 2-O 2)-M n+ (M n+ = Sr 2+, Ca 2+, Zn 2+, Lu 3+, Y 3+ and Sc 3+; TMC, 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane). We demonstrate that the Ca 2+ and Sr 2+ complexes showed similar electrochemical properties and reactivities in one-electron oxidation or reduction reactions. However, the properties and reactivities of complexes formed with stronger Lewis acidities were found to be markedly different. In conclusion, complexes that contain Ca 2+ or Sr 2+ ions were oxidized by an electron acceptor to release O 2, whereas the release of O 2 did not occur for complexes that bind stronger Lewis acids. ...

In a BIM for a mononuclear centre, the central atom (metal) is written first, followed by the endogenous ligands (amino acid residues), and then the exogenous ligands, e.g. water. If the ligating atom needs to be indicated to avoid ambiguity, the symbol for this is separated from the ligand symbol by a dot, e.g. NE.His stands for the Nε atom of a His residue. This is a simplistic description that does not take into account the stereochemistry at the metal atom. The polyhedral symbol is not mandatory for it may be unknown. It also does not make sense for polynuclear metal centres (see below).. Example 4.1 in Table 4 shows a mononuclear centre found in the blue copper protein azurin. In this centre, one copper atom is coordinated by the Nδ atoms of two His residues, one mainchain oxygen derived from Gly, one Sδ atom of a Met residue and one Sγ atom of a Cys residue. The coordination geometry is trigonal bipyramidal (TBPY-5; the polyhedral symbols used are as in Table S3 in Additional file ...

A method of forming a programmable conductor memory cell array is disclosed wherein metal and chalcogenide glass are co-sputtered to fill an array of cell vias in a prepared substrate. The prepared substrate is heated above room temperature before the metal and chalcogenide glass film is deposited, and the heating is maintained throughout the deposition. The resulting metal/chalcogenide glass film has good homogeneity, a desired ratio of components, and has a regular surface.

Chalcogenide glass fibers are promising photonic tools to develop Fiber Evanescent Wave Spectroscopy (FEWS) optical sensors working in the mid-infrared region. Numerous pioneering works have already been carried out showing their efficiency, especially for bio-medical applications. Nevertheless, this technology remains confined to academic studies at the laboratory scale because chalcogenide glass fibers are difficult to shape to produce reliable, sensitive and compact sensors. In this paper, a new method for designing and fabricating a compact and robust sensing head with a selenide glass fiber is described. Compact looped sensing heads with diameter equal to 2 mm were thus shaped. This represents an outstanding achievement considering the brittleness of such uncoated fibers. FEWS experiments were implemented using alcoholic solutions as target samples showing that the sensitivity is higher than with the routinely used classical fiber. It is also shown that the best compromise in term of sensitivity is

the topic of dioxygen activation and homogeneous catalytic oxidation by way of steel complexes has been within the concentration of recognition during the last two decades. The common curiosity is illustrated through its routine presence one of the periods and topic components of significant overseas meetings on quite a few facets of bioinorganic and coordination chemistry in addition to catalysis. the main admired examples are ICCC, ICBIC, EUROBIC, ISHC, and naturally the ADHOC sequence of conferences targeting the topic itself. equally, the variety of unique and overview papers dedicated to a variety of features of dioxygen activation are at the upward push. This pattern is due evidently to the relevance of catalytic oxidation to organic strategies similar to dioxygen shipping, and the motion of oxygenase and oxidase enzymes relating to metabolism. The structural and useful modeling of metalloenzymes, quite of these containing iron and copper, by way of low-molecular complexes of iron, copper, ...

The preparation in the kilogram-scale of uniform polymermetallic nanomaterials using conventional techniques is rather difficult. The creation and future utilization of such types of nano-size systems require the development of new technological processes.. A universal method of introduction of metall-containing nano-particles in polymeric matrices has been developed, which allows the fabrication of large amounts (kilogram-scale) of polymer nanoparticle composites. The encapsulation was done by thermal decomposition of metallcontaining compounds (MRn; M = Cr, Mo, W, Ti, Zr, Fe, Co, Ni, Pd, Pt, Cu; R = CO, HCOO, CH3COO, C6H5CH2) in solution-melt of polymer (polyethylene, polypropylene, polytetrafluoroethylene, polyamide, polyarylate, polycarbonate, polysterene, polyethers, polyphenyleneoxide, siloxane). For the preparation of heterometallic nanoparticles we used as a rule available heterometallic MCC; in some case labile heterometallic MCC were prepared in solution immediately before adding in ...

Title: Toxic Metals and Oxidative Stress Part I: Mechanisms Involved in Me-tal induced Oxidative Damage. VOLUME: 1 ISSUE: 6. Author(s): Nuran Ercal, Hande Gurer-Orhan and Nukhet Aykin-Burns. Affiliation:Department of Chemistry,University of Missouri-Rolla, 142 Schrenk Hall, Rolla, MO 65409-0010,USA.. Abstract: Toxic metals (lead, cadmium, mercury and arsenic) are widely found in our environment. Humans are exposed to these metals from numerous sources, including contaminated air, water, soil and food. Recent studies indicate that transition metals act as catalysts in the oxidative reactions of biological macromolecules therefore the toxicities associated with these metals might be due to oxidative tissue damage. Redox-active metals, such as iron, copper and chromium, undergo redox cycling whereas redox-inactive metals, such as lead, cadmium, mercury and others deplete cells major antioxidants, particularly thiol-containing antioxidants and enzymes. Either redox-active or redox-inactive metals ...

394:154-157 9Jul98], investigated single atom electrical contacts of Pb, Al, Nb, and Au, finding that the number of conduction channels through the contacts can be predicted from the valence orbitals of the atoms. Very roughly speaking, they found that the number of quantum channels is bounded by the number of valence orbitals in the contact atom. The conductance, however, is also limited by the transmission probability of each of the channels.. The authors measured conductance as a function of distance in each type of contact. Measuring the conductance gives the sum of the conductances of the quantum channels. The authors also measured current as a function of voltage at a number of distances for each type of contact. This additional information let them extract the individual transmission probabilities (Tn) of each of the channels.. They placed the single atom contacts between superconductors. In this geometry, single electrons can only tunnel if the voltage difference is large enough to break ...
As I understand it (but my understanding is very heuristic, so I may be significantly oversimplifying in what follows), the inflationary era was an era in which the inflaton field was in a state called the false vacuum, which was a vacuum state in that era, but which was no longer a vacuum state when the universe underwent a phase transition. After that transition, the inflaton field changed state to the state it is in now, called the true vacuum, which (as far as we can tell) is its lowest energy state now and for the rest of the universes history; but this state has much *less* energy than the false vacuum state, so the phase transition resulted in a lot of energy being transferred into the other quantum fields (which were in their vacuum states before the transition), the ones we now observe as the matter and radiation in the universe. (Of course the energy density in these fields now is much smaller than it was right after the phase transition, due to the expansion of the universe ...
First-principles calculations have been used to study the structural and electronic properties of BaS1-xSex ternary alloy using full-potential muffin-tin orbitals (FP-LMTO) method within density functional theory (DFT). In this approach, the local-density approximation (LDA) and generalized gradient approximation (GGA) are used for the exchange-correlation (XC) potential. The effect of composition on lattice parameter, bulk modulus, band gap and effective mass was investigated. The deviations of the lattice constant from Vegards law and the bulk modulus from linear concentration depend- ence were observed for BaS1-xSex alloy. The microscopic origins of bowing parameter were explained using approach of Zunger and co-workers. Accordance is found from the comparison of our results with other experimental and theo- retical calculations.
Waveguides according to this invention have a chalcogenide glass core that comprises Se and one or both of As and Ge, and further comprises one or more dopant elements selected from the elements that cause a change in optical energy gap Eg of the glass core. The amount of dopant is selected such that Eg is equal to or less than a 2-photon energy 2hν, where h is Plancks constant and ν=c/λ, where c is the speed of light in vacuum and λ is an operating wavelength. The dopant elements furthermore are selected such that the chalcogenide glass core has a nonlinear refractive index n2 greater than 200n2 (SiO2), where n2 (SiO2) is the nonlinear index of silica at λ. Typically, λ is about 1.55 μm. Exemplary, the dopant elements are selected from Sb, Bi, Sn, Pb, In, Tl, Cu, Ag and S. Currently preferred dopants are Te, Sb, Tl, Cu and Ag. Waveguides according to the invention are advantageously used in all-optical switches, optical logic elements and other means for optical processing of optical pulses.

Single-chain magnets (SCMs) are materials composed of magnetically isolated one-dimensional (1D) units exhibiting slow relaxation of magnetization. The occurrence of SCM behavior requires the fulfillment of stringent conditions for exchange and anisotropy interactions. Herein, we report the synthesis, the structure, and the magnetic characterization of the first actinide-containing SCM. The 5f-3d heterometallic 1D chains [{[UO2(salen)(py)][M(py) 4](NO3)}]n, (M=Cd (1) and M=Mn (2); py=pyridine) are assembled trough cation-cation interaction from the reaction of the uranyl(V) complex [UO2(salen)py][Cp*2Co] (Cp*=pentamethylcyclopentadienyl) with Cd(NO3)2 or Mn(NO3)2 in pyridine. The infinite UMn chain displays a high relaxation barrier of 134±0.8 K (93±0.5 cm-1), probably as a result of strong intra-chain magnetic interactions combined with the high Ising anisotropy of the uranyl(V) dioxo group. It also exhibits an open magnetic hysteresis loop at ...
The localized orbitals in your best Lewis structure can interact strongly. A filled bonding or lone pair orbital can act as a donor and an empty or filled bonding, antibonding, or lone pair orbital can act as an acceptor. These interactions can strengthen and weaken bonds. For example, a lone pair donor->antibonding acceptor orbital interaction will weaken the bond associated with the antibonding orbital. Conversly, an interaction with a bonding pair as the acceptor will strengthen the bond. Strong electron delocalization in your best Lewis structure will also show up as donor-acceptor interactions ...

NaCl and MgCl2 are ionic chlorides. Since a large amount of energy is required to separate the ions, the melting point is high.. AlCl3 and SiCl4 are molecular covalent chlorides, and so only intermolecular forces exist between the molecules. The melting points are thus much lower than the ionic chlorides.. AlCl3 actually exists in polymeric form in the solid state, which is converted to a dimeric form in the gas phase. This is because the aluminium atom is electron deficient - it has only 3 of its four valence orbitals occupied, so it has an empty orbital with which it can accept a lone pair of electrons from a Cl atom on an adjacent monomer. At high temperatures, it reverts to a simple molecular structure.. PCl5 is ionic so its melting point is thus high. On heating, however, it reverts to a simple covalent structure and sublimes..

This is because the aluminium atom is electron deficient - it has only 3 of its four valence orbitals occupied, so it has an empty orbital with which it can accept a lone pair of electrons from a Cl atom on an adjacent monomer. At high temperatures, it reverts to a simple molecular structure.. PCl5 is ionic so its melting point is thus high. On heating, however, it reverts to a simple covalent structure and sublimes..

Recently crystallography and spectroscopy have reached a level of experimental sophistication and theoretical and computational advancements such that it is possible to understand the structure of even the most complex molecular systems, such as, proteins. One community derives information from average atomic charge densities from X-ray data and the other from valence orbital electron densities based on vibrational spectroscopy data. The modern generation of synchrotrons and the powerful free electron lasers (X-FEL) offer new opportunities and exciting challenges in structural science, but they will require a coordinated approach of complementary methods if they are to achieve maximum impact. We are constantly improving technical and computational methods to accelerate and automate characterisation processes and this is crucial to the fields to be explored in this meeting ...

The LCP group is dedicated to the material sciences of chalcogenide compound semiconductors, e.g., Cu(In,Ga)(S,Se)2 (Chalcopyrites) and Cu2ZnSn(S,Se)4 (Kesterites), and their application in solar cells and commercial photovoltaic modules. Our scientific interest is focused on the fundamental physics of heterojunction solar cells and on the exploration of efficiency-limiting properties of the involved materials and interfaces with particular attention to lateral and vertical inhomogenieties and matastable phenomena. To address specific problems we employ a broad spectrum of diagnostic tools comprising methods from the following categories: ...
We combine inorganic synthesis, chemical biology and spectroscopy to relate the structures of metal centres to reactivity. Many of the systems we study are paramagnetic, and we use electron paramagnetic resonance (EPR) and electron-nuclear double resonance (ENDOR) to study paramagnetic metal centres and radical chemistry. We also use NMR extensively to characterise diamagnetic species produced by redox processes, and to study reaction products and kinetics in catalytic systems. These methods are supplemented by DFT calculations of molecular properties and spectroscopic parameters. ...
Quantum dot (QD), or semiconductor nanocrystal, thin films are being explored for making solution-processable devices due to their size- and shape-tunable bandgap and discrete higher energy electronic states. While DNA has been extensively used for the self-assembly of nanocrystals, it has not been investigated for the simultaneous conduction of multiple energy charges or excitons via exciton shelves (ES) formed in QD-DNA nano-bioelectronic thin films. Here, we present studies on charge conduction through exciton shelves, which are formed via chemically coupled QDs and DNA, between electronic states of the QDs and the HOMO-LUMO levels in the complementary DNA nucleobases. While several challenges need to be addressed in optimizing the formation of devices using QD-DNA thin films, a higher charge collection efficiency for hot-carriers and our detailed investigations of charge transport mechanism in these thin films highlight their potential for applications in nano-bioelectronic devices and ...

To generate larger supramolecular assemblies porphyrin axial ligand coordination may be combined with hydrogen bonding recognition sites. If these recognition elements are not to interfere with each other then the hydrogen bond donors and acceptors must not compete as axial ligands for the porphyrin, and the ligand group should not compete for hydrogen bonds.. Based on these principles Kuroda and coworkers reported the assembly of a heterometallic porphyrin trimer.122 The dialkyl tartrate derivative 71 was found to bind to porphyrin 72 by formation of four hydrogen bonds to the amide protons of 72. The NMR spectrum of a mixture of 71 and 72 in CDCl3 displayed resonances at -3.81 and -4.13 ppm which were attributed to the hydroxyl protons of 71, shielded due to their close approach to the porphyrin, and split into two peaks as a result of the unsymmetrical aryl substitution pattern of 72. The association constant was estimated as , 105 M-1 by spectrophotometric titration. The pyridyl groups of 71 ...
The influence of ligand substitution on the photochromic properties of [Ru(bpy)2(OSOR)]∙PF6 compounds (bpy = 2,2-bipyridine, OSO = 2-methylsulfinylbenzoate) dissolved in propylene carbonate is studied by UV/VIS laser-spectroscopy as a function of temperature and exposure. The group R is either Bn (CH2C6H5), BnCl or BnMe. The photochromic properties originate from a phototriggered linkage isomerization located at the SO ligand. It is shown that the thermal stability of the studied compounds can be varied by ligand substitution in the range of 1.6 × 103 s to 3.9 × 104 s. In contrast, absorption spectra of ground and metastable states as well as the characteristic exposure of the photochromic response remain unchanged. The results are explained in the frame of photoinduced linkage isomerization located at the SO ligand.. ©2010 Optical Society of America. Full Article , PDF Article ...

Arsenic (As). Diagram of the nuclear composition, electron configuration, chemical data, and valence orbitals of an atom of arsenic-75 (atomic number: 33), the most common isotope of this element. The nucleus consists of 33 protons (red) and 42 neutrons (orange). 33 electrons (white) successively occupy available electron shells (rings). The stability of an elements outer (valence) electrons determines its chemical and physical properties. Arsenic, which is extremely toxic, is used as a dopant in semiconductors. It is a metalloid in group 15, period 4, and the p-block of the periodic table. It sublimes (goes from solid to gas) at 615 degrees Celsius. - Stock Image C018/3714
In this thesis, quantum-mechanical calculations within density-functional theory on metallic systems are presented. The overarching goal has been to investigate effects of disorder. In particular, one of the properties investigated is the bindingenergy shifts for core electrons in binary alloys using different theoretical methods. These methods are compared with each other and with experimental results. One such method, the so-called Slater-Janak transition state method relies on the assumption that the single-particle eigenvalues within density-functional theory are linear functions of their respective occupation number. This assumption is investigated and it is found that while the eigenvalues to a first approximation show linear behavior, there are also nonlinearities which can influence the core-level binding energy shifts.. Another area of investigation has been iron based alloys at pressures corresponding to those in the Earths inner core. This has been done for the hexagonal close packed ...

A fairly large portion of patients receiving surgical or intensive care will need mechanical ventilation at some point. The potential ventilator-induced lung injury (VILI) is thus of interest. One of the main causal factors in VILI is the cyclic energy shifts, i.e. tidal volumes, in the lung during mechanical ventilation. The problem can be approached in two ways. Firstly, one can utilize apneic oxygenation and thus not cause any tidal injuries at all. Secondly, and more traditionally, one can simply lower the tidal volumes and respiratory rates used. The following describes a series of animal experiments exploring these options.. In the first two papers, I explored and improved upon the methodology of apneic oxygenation. There is a generally held belief that it is only possible to perform apneic oxygenation by prior denitrogenation and by using 100% oxygen during the apnea. As 100% oxygen is toxic, this has prevented apneic oxygenation from more widespread use. The first paper proves that it is ...
