Oxidoreductases
The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)
Hydrogen
The first chemical element in the periodic table. It has the atomic symbol H, atomic number 1, and atomic weight [1.00784; 1.00811]. It exists, under normal conditions, as a colorless, odorless, tasteless, diatomic gas. Hydrogen ions are PROTONS. Besides the common H1 isotope, hydrogen exists as the stable isotope DEUTERIUM and the unstable, radioactive isotope TRITIUM.
Formate Dehydrogenases
Flavoproteins that catalyze reversibly the reduction of carbon dioxide to formate. Many compounds can act as acceptors, but the only physiologically active acceptor is NAD. The enzymes are active in the fermentation of sugars and other compounds to carbon dioxide and are the key enzymes in obtaining energy when bacteria are grown on formate as the main carbon source. They have been purified from bovine blood. EC 1.2.1.2.
Electron Transport
Thiocapsa roseopersicina
Nitrates
Paraquat
Oxidation-Reduction
A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471).

Nitrites
Salts of nitrous acid or compounds containing the group NO2-. The inorganic nitrites of the type MNO2 (where M=metal) are all insoluble, except the alkali nitrites. The organic nitrites may be isomeric, but not identical with the corresponding nitro compounds. (Grant & Hackh's Chemical Dictionary, 5th ed)
NADP
Nicotinamide adenine dinucleotide phosphate. A coenzyme composed of ribosylnicotinamide 5'-phosphate (NMN) coupled by pyrophosphate linkage to the 5'-phosphate adenosine 2',5'-bisphosphate. It serves as an electron carrier in a number of reactions, being alternately oxidized (NADP+) and reduced (NADPH). (Dorland, 27th ed)
Escherichia coli
A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Pre-steady-state kinetics of the reactions of [NiFe]-hydrogenase from Chromatium vinosum with H2 and CO. (1/29)
Results are presented of the first rapid-mixing/rapid-freezing studies with a [NiFe]-hydrogenase. The enzyme from Chromatium vinosum was used. In particular the reactions of active enzyme with H2 and CO were monitored. The conversion from fully reduced, active hydrogenase (Nia-SR state) to the Nia-C* state was completed in less than 8 ms, a rate consistent with the H2-evolution activity of the enzyme. The reaction of CO with fully reduced enzyme was followed from 8 to 200 ms. The Nia-SR state did not react with CO. It was discovered, contrary to expectations, that the Nia-C* state did not react with CO when reactions were performed in the dark. When H2 was replaced by CO, a Nia-C* EPR signal appeared within 11 ms; this was also the case when H2 was replaced by Ar. With CO, however, the Nia-C* state decayed within 40 ms, due to the generation of the Nia-S.CO state (the EPR-silent state of the enzyme with bound CO). The Nia-C* state, induced after 11 ms by replacing H2 by CO in the dark, could be converted, in the frozen enzyme, into the EPR-detectable state with CO bound to nickel (Nia*.CO) by illumination at 30 K (evoking the Nia-L* state), followed by dark adaptation at 200 K. This can be explained by assuming that the Nia-C* state represents a formally trivalent state of nickel, which is unable to bind CO, whereas nickel in the Nia-L* and the Nia*.CO states is formally monovalent. (+info)Diphenylene iodonium as an inhibitor for the hydrogenase complex of Rhodobacter capsulatus. Evidence for two distinct electron donor sites. (2/29)
The photosynthetic bacterium Rhodobacter capsulatus synthesises a membrane-bound [NiFe] hydrogenase encoded by the H2 uptake hydrogenase (hup)SLC structural operon. The hupS and hupL genes encode the small and large subunits of hydrogenase, respectively; hupC encodes a membrane electron carrier protein which may be considered as the third subunit of the uptake hydrogenase. In Wolinella succinogenes, the hydC gene, homologous to hupC, has been shown to encode a low potential cytochrome b which mediates electron transfer from H2 to the quinone pool of the bacterial membrane. In whole cells of R. capsulatus or intact membrane preparation of the wild type strain B10, methylene blue but not benzyl viologen can be used as acceptor of the electrons donated by H2 to hydrogenase; on the other hand, membranes of B10 treated with Triton X-100 or whole cells of a HupC- mutant exhibit both benzyl viologen and methylene blue reductase activities. We report the effect of diphenylene iodonium (Ph2I), a known inhibitor of mitochondrial complex I and of various monooxygenases on R. capsulatus hydrogenase activity. With H2 as electron donor, Ph2I inhibited partially the methylene blue reductase activity in an uncompetitive manner, and totally benzyl viologen reductase activity in a competitive manner. Furthermore, with benzyl viologen as electron acceptor, Ph2I increased dramatically the observed lagtime for dye reduction. These results suggest that two different sites exist on the electron donor side of the membrane-bound [NiFe] hydrogenase of R. capsulatus, both located on the small subunit. A low redox potential site which reduces benzyl viologen, binds Ph2I and could be located on the distal [Fe4S4] cluster. A higher redox potential site which can reduce methylene blue in vitro could be connected to the high potential [Fe3S4] cluster and freely accessible from the periplasm. (+info)Nitrate reductase system in Staphylococcus aureus wild type and mutants. (3/29)
Respiratory nitrate reductase with lactate as a hydrogen donor has been studied in cells and spheroplast preparations of wild type and heme-deficienct mutants of Staphylococcus aureus. The activity is rapidly induced when suspensions of aerobically grown cells are incubated without aeration in a complete medium with nitrate. In ruptured spheroplast preparations, the activity with lactate as the donor is located in the membrane fraction, whereas at least 50% of the activity assayed with reduced benzyl viologen is in the cytoplasm. The reductase is inhibited by azide and cyanide, and the lactate-linked system is also sensitive to oxamate, 2-heptyl-4-hydroxyquinoline-N-oxide, dicoumarol, and p-chloromercuribenzoate. An inactive form of the reductase is apparently made during induction with tungstate; this can be activated by subsequent incubation with molybdate in the presence of chloramphenicol. Nitrate reductase activity with reduced benzyl viologen as the donor is induced in suspensions of heme-deficient mutants in the presence or absence of heme. The proportion of cytoplasmic activity is increased in the absence of heme. The staphylococcal nitrate reductase has many of the characteristics commonly associated with the respiratory enzyme in other organisms, but the apparent predominance of cytoplasmic activity is unusual. (+info)An autocatalytic step in the reaction cycle of hydrogenase from Thiocapsa roseopersicina can explain the special characteristics of the enzyme reaction. (4/29)
A moving front has been observed as a special pattern during the hydrogenase-catalyzed reaction of hydrogen uptake with benzyl viologen as electron acceptor in a thin-layer reaction chamber. Such fronts start spontaneously and at random times at different points of the reaction chamber; blue spheres are seen expanding at constant speed and amplitude. The number of observable starting points depends on the hydrogenase concentration. Fronts can be initiated by injecting either a small amount of completed reaction mixture or activated hydrogenase, but not by injecting a low concentration of reduced benzyl viologen. These characteristics are consistent with an autocatalytic reaction step in the enzyme reaction. The special characteristics of the hydrogen-uptake reaction in the bulk reaction (a long lag phase, and the enzyme concentration dependence of the lag phase) support the autocatalytic nature. We conclude that there is at least one autocatalytic reaction step in the hydrogenase-catalyzed reaction. The two possible autocatalytic schemes for hydrogenase are prion-type autocatalysis, in which two enzyme forms interact, and product-activation autocatalysis, where a reduced electron acceptor and an inactive enzyme form interact. The experimental results strongly support the occurrence of prion-type autocatalysis.

(+info)Steroid transhydrogenase activity of 3-ketosteroid-delta 1-dehydrogenase from Nocardia corallina. (7/29)
3-Ketosteroid-delta 1-dehydrogenase from Nocardia corallina catalyzes transhydrogenation of 3-keto-4-ene-steroid to 3-keto-1,4-diene-steroid e.g., progesterone to 1,4-androstadiene-3,17-dione. The reaction proceeded linearly at first and then soon slowed down owing to equilibration. The turnover number of this reaction was of the same magnitude as that of the dehydrogenation of 3-keto-4-ene-steroid. The pH optimum was 8.4, which is lower than that of the dehydrogenase reaction. The enzyme has a wide specificity for hydrogen acceptor steroids. The Km' and Kmax' values for these steroids and the values of the corresponding 3-keto-4-ene-steroids were compared. Kinetic studies of the steroid transhydrogenase reaction demonstrated a typical ping-pong mechanism. The enzyme oxidized 1,2-tritiated progesterone and transferred the tritium atoms to the reaction product, 4-androstene-3,17-dione, and water. Transhydrogenation in D2O resulted in the incorporation of a deuterium atom into the C2-position of 4-androstene-3,17-dione. The results indicate that the enzyme catalyzes C1, C2-trans axial abstraction of hydrogen atoms from progesterone, transfer of the 1 alpha-hydrogen to the C1-position of 1,4-androstadiene-3, 17-dione and release of the 2 beta-hydrogen to water. Reaction schemes based on the experimental results are proposed. The enzyme also catalyzes the reduction of 3-keto-1,4-diene-steroids with reduced benzyl viologen.

Methyl7
- Methyl viologen dichloride hydrate is a well-known electron acceptor since it is having similar reduction potential value compared to the conduction band (−0.44 V) of TiO 2 . (sigmaaldrich.com)
- Methyl viologen dichloride hydrate can be used as an electron transfer agent, which provides insights into the dynamics of the excited state of quantum dot materials. (sigmaaldrich.com)
- The viologen paraquat (R = methyl), is a widely used herbicide. (wikipedia.org)
- When the alkylating agent is a small alkyl halide, such as methyl chloride or methyl bromide, the viologen salt is often water-soluble. (wikipedia.org)
- Common derivatives are methyl (see paraquat), long chain alkyl, and benzyl. (wikipedia.org)
- The xanthine/xanthine oxidase system provides a slow continuous reduction of the indicator dye and the flavin in the presence of benzyl viologen (BV) or methyl viologen (MV) which ensures the rapid equilibration of reducing equivalents. (bio-protocol.org)
- Das, Samar K. (2011) Ion-pair charge transfer complex with near-IR absorption: Synthesis, crystal structure and properties of [Hb] 2 [Cu(mnt) 2 ] (Hb = 1-(4-((1H-imidazol-1-yl)methyl)benzyl)-1H-imidazol-3-ium) Journal of Molecular Structure, 990 (1-3). (ias.ac.in)
Chemicals1
- Because some of the components used in this method are low potential chemicals and proteins (viologen, reference dyes, and many flavoproteins) that are readily oxidized by even trace amounts of oxygen, a requirement for this system is that strict anaerobiosis be maintained. (bio-protocol.org)
Reduction4
- Viologens are called so, because these compounds produce violet color on reduction [violet + Latin gen, generator of]. (wikipedia.org)
- Other viologens have been commercialized because they can change color reversibly many times through reduction and oxidation. (wikipedia.org)
- Viologens have been commercialized as electrochromic systems because of the highly reversible and dramatic change color upon reduction and oxidation. (wikipedia.org)
- In addition, the mutation in the FrdD peptide caused an almost total loss of the ability of the enzyme to oxidize either menaquinol-6, a physiological donor for fumarate reduction, or reduced benzyl viologen. (mst.edu)
Ability1
- The toxicity of the 2,2'-, 4,4'-, or 2,4'-bipyridylium-based viologens is related to their ability to form stable free radicals. (wikipedia.org)
Potential2
- Viologen catalysts have been reported to have the potential to oxidize glucose and other carbohydrates catalytically in a mildly alkaline solution, which makes direct carbohydrate fuel cells possible. (wikipedia.org)
- Compound 3 is a very strong reducing agent, with a redox potential of −1.48 V. The widely used herbicide paraquat is a viologen. (wikipedia.org)
