The ndhB- and psaE- mutants of the cyanobacterium Synechocystis sp. PCC 6803 are partly deficient in PSI-driven cyclic electron transport. We compared photoinhibition in these mutants to the wild type to test the hypothesis that PSI cyclic electron transport protects against photoinhibition. Photoinhibitory treatment greatly accelerated PSI cyclic electron transport in the wild type and also in both the mutants. The psaE- mutant showed rates of PSI cyclic electron transport similar to the wild type under all conditions tested. The ndhB- mutant showed much lower rates of PSI cyclic electron transport than the wild type following brief dark adaptation but exceeded wild type rates after exposure to photoinhibitory light. The wild type and both mutants showed similar rates of photoinhibition damage and photoinhibition repair at PSII. Photoinhibition at PSI was much slower than at PSII and was also similar between the wild type and both mutants, despite the known instability of PSI in the psaE- ...
Electron Transport Chain and Energy Production In cellular biology, the electron transport chain is one of the steps in your cells processes that make energy from the foods you eat.à It is the third step of aerobic cellular respiration. Cellular respiration is the term for how your bodys cells make energy from food consumed. The electron transport chain is where most of the energy cells need to operate is generated. This chain is actually a series of protein complexes and electron carrier molecules within the inner membrane of cell mitochondria, also known as the cells powerhouse. Oxygen is required forà aerobic respirationà as the chain terminates with the donation of electrons to oxygen.à Key Takeaways: Electron Transport Chain The electron transport chain is a series of protein complexes and electron carrier molecules within the inner membrane of mitochondria that generate ATP for energy.Electrons are passed along the chain from protein complex to protein complex until they are donated to ...
The electron transfer properties of proteins are normally measured as molecularly averaged ensembles. Through these and related measurements, proteins are widely regarded as macroscopically insulating materials. Using scanning tunnelling microscopy (STM), we present new measurements of the conductance through single-molecules of the electron transfer protein cytochrome b562 in its native conformation, under pseudo-physiological conditions. This is achieved by thiol (SH) linker pairs at opposite ends of the molecule through protein engineering, resulting in defined covalent contact between a gold surface and a platinum-iridium STM tip. Two different orientations of the linkers were examined: a long-axis configuration (SH-LA) and a short-axis configuration (SH-SA). In each case, the molecular conductance could be gated through electrochemical control of the heme redox state. Reproducible and remarkably high conductance was observed in this relatively complex electron transfer system, with ...
Electron transfer reactions constitute a fundamental chemical process and are of intrinsic importance in biology, chemistry, and the emerging field of nanotechnology. Electron transfer reactions proceed generally in a few limiting regimes: nonadiabatic electron transfer, adiabatic electron transfer and solvent controlled electron transfer. Behavior between some of these regimes was examined by varying the solvents in which the reaction occurs i.e., the different polarization relaxation. In a fast solvent, such as acetonitrile, the electron transfer occurs in the nonadiabatic regime over a broad temperature range; in a slow solvent, such as N-methylacetamide (NMA) and N-methylpropionamide (NMP), the electron transfer reaction occurs in the nonadiabatic regime of high temperature but occurs in the solvent controlled regime as the temperature decreases. The semiclassical model was compared to the electron transfer rate data in the nonadiabatic regime and the Zusman model was compared to the ...
Amino acid radicals are key redox intermediates in several natural enzymes including Cytochrome c peroxidase, DNA photolyase, ribonucletide reductase, cytochrome c oxidase and photosystem II. Electron transfer from amino acids is often coupled to deprotonation and this thesis concerns the coupling of electron transfer from tyrosine and tryptophan to trisbipyridineruthenium(III) with deprotonation in model complexes. Specifically the mechanisms for these proton coupled electron transfer reactions have been studied and the controlling parameters have been identified, the possible mechanisms being stepwise electron transfer followed by deprotonation and deprotonation followed by electron transfer or concerted electron transfer/deprotonation.. Proton coupled electron transfer reactions have been studied using nano-second flash photolysis in water solution and the effect of pH, temperature, reaction driving force, deuteration and nature of the amino acid has been determined. I have shown that the ...
A continuous supply of energy in the form of ATP is essential to the maintenance of life. In most eukaryotes, it is achieved by oxygen-dependent energy production and the mitochondrial electron transport chain plays a central role in ATP production. In higher eukaryotes, the electron transport chain comprises four integral membrane protein complexes namely, NADH:ubiquinone oxidoreductase (complex I), succinate:ubiquinone oxidoreductase (complex II), ubiquinol:cytochrome c oxidoreductase/ cytochrome bc1 complex (complex III) and cytochrome oxidase (complex IV). The electrons are transferred from NADH and succinate to oxygen through these series of enzymatic complexes of the inner mitochondrial membrane and oxygen is reduced to water. This releases energy and generates a proton gradient across mitochondrial membrane by pumping protons into the intermembrane space. The energy of oxidation of hydrogen is used to phosphorylate ADP into ATP. This ATP generation is catalysed by ATP synthase complex ...
TY - JOUR. T1 - Tunneling time for electron transfer reactions. AU - Nitzan, Abraham. AU - Jortner, Joshua. AU - Wilkie, Joshua. AU - Burin, Alexander L.. AU - Ratner, Mark A.. PY - 2000/6/22. Y1 - 2000/6/22. N2 - The tunneling time for nonadiabatic electron transfer reactions described within the superexchange model is estimated using a Biittiker type internal clock: the electron is taken to possess two internal spin states that are weakly coupled on the bridge. By studying the transition probability between these channels during the tunneling process the traversal time through the bridge can be estimated. Like the Büttiker-Landauer result it is linear in the bridge length, but its dependence on the barrier energy UB approaches the Büttiker-Landauer form only in the limit of strong interstate coupling (broad band). In the "normal" superexchange (weak coupling) limit it is inversely proportional to the barrier energy.. AB - The tunneling time for nonadiabatic electron transfer reactions ...

We have studied long-range electron transfer through various lengths of helical peptides from 8 mer (24 Å) up to 80 mer (120 Å) in self-assembled monolayers prepared on a gold surface. Helical peptides carrying a redox-active ferrocene unit and a disulfide group at the respective terminals were synthesized and immobilized on gold via a gold-sulfur linkage to form a well-defined monolayer with vertical helix orientation, and the electron transfer from the ferrocene unit to gold through the helical peptides was studied by electrochemistry. The electron transfer showed a very shallow distance dependence and high activation energies, both of which are characteristic of a hopping mechanism. Detailed theoretical calculations successfully demonstrated that a hopping mechanism with the amide groups as hopping sites is responsible for the long-range electron transfer, which enables ultralong-range electron transfer over 120 Å with the 80 mer helical peptide.
Disponible ahora en Iberlibro.com - ISBN: 9780841216754 - Hard Cover - American Chemical Society - 1990 - Condición del libro: Fine - Not Given - No Jacket - Electron transfer has become a unifying concept for widely disparate groups of researchers. It serves as the bridge between scientists studying electron-transfer processes in solids and those studying the same processes between metal centers in proteins and other biologically significant molecules. This broad and fundamental subject matter is in a state of intellectual ferment, as electron transfer is investigated in such unusual materials as proteins and peptides. Semiconductor and tunneling models, which have often been used to explain conducting properties in solids, also apply to many aspects of long-range biological electron transfer. This book has 470 pages and is illustrated throughout.
The electron transfer rates at the steady state are evaluated in terms of the Gaussian wave packet motion on free energy curves in the two- and three-surface models in the presence of inertial effects. The autocorrelation functions of the solvent polarization coordinate are fitted to the results of recent molecular dynamics simulations. It is found that the inertial effects are particularly important for the electron transfer processes in acetonitrile and water. They constitute an impeding factor in the wave packet motion. The neglect of the inertial part of the solvent autocorrelation function gives underestimation of the electron transfer rate coefficient ...

Individual bacteria use multiple electron transport chains, often simultaneously. Bacteria can use a number of different electron donors, a number of different dehydrogenases, a number of different oxidases and reductases, and a number of different electron acceptors. For example, E. coli (when growing aerobically using glucose as an energy source) uses two different NADH dehydrogenases and two different quinol oxidases, for a total of four different electron transport chains operating simultaneously.. A common feature of all electron transport chains is the presence of a proton pump to create a transmembrane proton gradient. Bacterial electron transport chains may contain as many as three proton pumps, like mitochondria, or they may contain only one or two. They always contain at least one proton pump.. In the present day biosphere, the most common electron donors are organic molecules. Organisms that use organic molecules as an energy source are called organotrophs. Organotrophs (animals, ...
Normal aerobic metabolism (via processes such as photosynthetic and respiratory electron transport chains) in plants yields varied reactive oxygen species (ROS) such as singlet oxygen (1O2), superoxide (O2.¬), hydrogen peroxide (H2O2), and the hydroxyl radical (OH¬). Among the major ROS, H2O2 is an important, relatively stable (under physiological conditions), water-soluble and a longer half-life exhibiting, non-radical w-electron reduction product of oxygen. It has ability to readily cross biological membranes. Literature clearly reflects a double role of H2O2 in normal and (biotic/abiotic)stressed plants. On one hand, H2O2 can be considered essential to plant life because of the involvement of its optimum concentrations in the regulation of specific biological/physiological processes such as photosynthetic functions, cell cycle, growth and development, and plant responses to biotic and abiotic stresses. On the other hand, severe damage to biomolecules such as cellular lipids and proteins and

N2 - Two closely related, rigidly linked porphyrin-naphthoquinone dyads have been prepared and studied using time-resolved fluorescence and absorption methods. Dyad 1, whose quinone carbonyl groups are relatively close to the porphyrin macrocycle, exhibits photoinduced electron-transfer rate constants that are virtually independent of solvent dielectric constant and temperature within the range 77-295 K. Dyad 2, which has a similar donor-acceptor linkage but whose quinone carbonyl groups are ∼2 Å farther from the porphyrin, features photoinduced electron-transfer rate constants that decrease with decreasing solvent dielectric constant. Electron transfer in ...

During a multistep synthesis, protecting groups are often employed for the amino group to reduce its basicity and nucleophilicity. The benzyl group is a common protecting group for amines. However, its deprotection involves harsh chemical conditions. ^ The purpose of this research is (1) seek a mild debenzylation method by a visible light induced electron transfer reaction, and (2) develop a novel visible light removable quinoline type protecting group for amines which offers some advantages over the benzyl group. ^ Photochemical debenzylation of benzylated tertiary amines was carried out using an inexpensive spotlight, a dye as a photosensitizer and acetonitrile-water as solvent. Illumination under nitrogen led to the cleanest reaction, though under oxygen the reaction was faster. The reaction was about ten times faster in the presence of a cupric salt. The presumed mechanism of reaction involves a photoinduced electron transfer, and a coordination involving cupric ion seems to improve the quantum
Spin-polarized electron transport through zigzag-edged graphene nanoislands is studied within the framework of the Pariser-Parr-Pople Hamiltonian. By including both short- and long-range electron-electron interactions, the electron conductance is calculated self-consistently for the hexagonal model on various substrates from which we are able to identify the effects of the many-body interactions in the electron transport. For the system in its lowest antiferromagnetic (AFM) state, the long-range interactions are shown to have negligible effect on the electron transport in the low-energy region in which the conductance is found quenched mainly by the short-range interactions. As the system is excited to its second AFM state, the short- and long-range interactions are found to have opposite effects on the electron transmission, i.e., the electron transmission is found to increase with either the suppression of the long-range interactions or the enhancement of the short-range interactions. When the ...
We discuss the conductance of a molecular bridge between mesoscopic electrodes supporting low-dimensional transport and bearing an internal structure. As an example for such nanoelectrodes we assume semi-infinite (carbon) nanotubes. In the Landauer scattering matrix approach, we show that the conductance of this hybrid is very sensitive to the geometry of the contact, unlike the usual behavior in the presence of bulk electrodes. ...

Highly (001)-textured, photoactive WSe2 thin films have been prepared by an amorphous solid-liquid-crystalline solid process promoted by palladium. By increasing the thickness of the Pd promoter film (≥10 nm) the structure and texture of the WSe2 films can be improved significantly. However, these as-crystallized WSe2 films are only weakly photoactive in a 0.5 М H2SO4 electrolyte under AM 1.5 solar irradiation which we attribute to an inefficient photogenerated charge transfer across the WSe2/electrolyte interface via the prevailing van der Waals planes of the WSe2 crystallites. In this work photochemically deposited platinum on the p-type WSe2 photocathode is used for an efficient electron transfer thus inducing the hydrogen evolution reaction. Upon illuminating the WSe2 photocathodes in a Pt-ion containing electrolyte, the photogenerated electrons reduce Pt+ to Pt leading to the precipitation of Pt islands, preferentially at edge steps of the WSe2, i.e. at the grain boundaries of the WSe2
In photosynthesis , 26 protein complexes and enzymes are required to go through the light and light independent reactions, a chemical process that transforms sunlight into chemical energy, to get glucose as end product , a metabolic intermediate for cell respiration. A good part of the protein complexes are uniquely used in photosynthesis. The pathway must go all the way through, and all steps are required, otherwise glucose is not produced. Also, in the oxygen evolving complex, which splits water into electrons, protons, and CO2, if the light-induced electron transfer reactions do not go all the five steps through, no oxygen, no protons and electrons are produced, no advanced life would be possible on earth. So, photosynthesis is a interdependent system, that could not have evolved, since all parts had to be in place right from the beginning. It contains many interdependent systems composed of parts that would be useless without the presence of all the other necessary parts. In these systems, ...
After the Krebs cycle is completed, oxygen enters the respiration pathway as the electron acceptor at the end of the electron transport chain.
Genome mapping of Mtb revealed that the genome contains genes encoding for a high number of cytochrome P450 enzymes (CYPs or P450s) that are involved in very specific and physiologically relevant pathways for the bacteria. Therefore, cytochrome P450 enzymes are investigated as targets for novel therapeutic agents. Sandra Ortega Ugalde and her AIMMS colleagues identified the reaction catalyzed by one of these CYPs, CYP130A1, shedding light into its physiological role. Furthermore, catalytic activity of mycobacterial CYPs is dependent on electron transfer from a NAD (P)H-ferredoxin-reductase and a ferredoxin. Ortega and her colleagues have improved the basic understanding of the selectivity, biochemical properties, and function of the iron-sulfur cluster-containing ferredoxin proteins in Mtb essential for the reconstitution of the cognate CYP catalytic system to aid in the development of new antibiotics. Finally, they are also conducting collaborative studies to synthetize specific and potent ...

Subunit VIII Of Cytochrome C Oxidase (Complex IV); Complex IV Is The Terminal Member Of The Mitochondrial Inner Membrane Electron Transport Chain
The reducing potential of NADH and FADH2 is converted to more ATP through an electron transport chain with oxygen as the "terminal electron acceptor". Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. This works by the energy released in the consumption of pyruvate being used to create a chemiosmotic potential by pumping protons across a membrane. This potential is then used to drive ATP synthase and produce ATP from ADP. Biology textbooks often state that 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).[2] However, this maximum yield is never quite reached due to losses (leaky membranes) as well as the cost of moving pyruvate and ADP into the mitochondrial matrix and current estimates range around 29 to 30 ATP per glucose ...

Our group aims to understand and monitor the dynamic formation of protein complexes in the context of membrane dynamics. For example, respiratory complexes of mitochondria that are arranged in a sequence of electron transfer reactions form rather stable supercomplexes (Rieger et al., 2017) in response to specific (energetic) states. On the other hand, membrane proteins transiently interact with soluble proteins, e.g. during membrane fission and fusion such as exocytosis. The interaction of membrane - membrane protein complexes or membrane - soluble protein complexes often is spatially and temporally restricted and thus difficult to survey. Yet, specific and spatially confined nano-organization mutually is prerequisite for local functionality (Beinlich et al., 2015). In our group, we use and implement diverse fluorescence-based microscopy techniques ranging from fluorescence lifetime imaging microscopy (FLIM) (Söhnel et al., 2016; Rieger et al., 2017) to superresolution imaging (Appelhans and ...

Oxygenic photosynthesis converts light-energy into chemical free energy by reducing NADP$\sp+$ to NADPH and producing ATP. Eukaryotic plants and algae as well as prokaryotic cyanobacteria and prochlorophytes have a similar photosynthetic apparatus. The light-driven reactions take place in the thylakoid membranes and three major membrane-intrinsic protein complexes carry out photosynthetic electron transfer, photosystem II, the cytochrome bf complex and photosystem I. To elucidate photosynthetic electron transport in oxygenic photosynthesis site-directed mutagenesis and biophysical techniques were employed in cyanobacteria which have the advantage over plants that they are easily genetically manipulated. This work focused on electron transfer linking the cytochrome bf complex and photosystem I, characterization of the plastoquinol oxidation site of the cytochrome bf complex and electron transfer within the PsaC polypeptide of the photosystem I complex. Major findings include (1) in vivo electron ...
