Abstract
An NADH--rubredoxin oxidoreductase previously isolated from Desulfovibrio gigas [LeGall, J. (1968) Ann. Inst. Pasteur 114, 109-115] has now been fully purified and further characterized. It contains two subunits of 27 kDa and 32 kDa. With two mid-point redox potentials of -295 mV and -325 mV, this FMN- and FAD-containing protein can induce the specific reduction of D. gigas rubredoxin. In contrast, rubredoxins from the other Desulfovibrio species or desulforedoxin from D. gigas show very low reaction rates with the same enzyme. The phylogenetic significance of the narrow specificity of the enzyme toward the rubredoxin from the same organism is discussed. The purified enzyme has NADH oxidase activity with H2O2 as a final product of O2 reduction. The reaction is half-inhibited by 4.2 microM p-chloromercuribenzoate, whereas cyanide and azide are not significant inhibitors in this reaction. The role of this protein as a part of the enzymic equipment that allows the formation of ATP in the presence of oxygen from the degradation of carbon reserves is discussed.

Abstract
In order to understand the electron transfer mechanisms for the [Fe] and [Ni-Fe] hydrogenases, a kinetic study of cytochrome c3 reduction has been undertaken. Cyclic voltammetry and controlled-potential amperometry techniques have been used to investigate the intermolecular electron-transfer reaction between cytochrome c3 and [Fe] hydrogenase from Desulfovibrio vulgaris Hildenborough. Electron-transfer cross-reactions between [Fe] or [Ni-Fe-Se] hydrogenase and cytochrome c3 from Desulfovibrio vulgaris Hildenborough or Desulfovibrio desulfuricans Norway have been studied. Some structural implications are considered from these experimental data.

Abstract
Structural studies carried out on a cross-linked complex between cytochrome c3 and ferredoxin I, both isolated from Desulfovibrio desulfuricans Norway, allowed the identification of the site of interaction between the two redox proteins. Staphylococcus aureus proteinase and chymotrypsin digestions led to characterization of peptides containing both cytochrome c3 and ferredoxin sequences. The cytochrome c3 sequences involved in the three isolated cross-linked peptides contained several lysine residues localized around the heme 4 crevice. This analysis stressed the peculiar role of lysines 100, 101, 103, 104 and 113, which could be considered as major cross-link sites, as opposed to the lysines 75, 79 and 82, which could be considered as minor cross-link sites. One cross-linked peptide, containing two ferredoxin sequences joined to one cytochrome c3 sequence, had been isolated, suggesting the possibility of more than one cross-link per covalent complex. All these results led to the identification of heme 4 of cytochrome c3 as the site of interaction for the ferredoxin I. This study confirms the proposal that could be deduced from the hypothetical structure of the complex built by computer graphics modelling (Cambillau, C., Frey, M., Mosse, J., Guerlesquin, F. and Bruschi, M. (1988) Proteins: struct., funct. genet. 4, 63-70).

Abstract
To specify electron exchanges involving Desulfovibrio desulfuricans Norway tetra-heme cytochrome c3, the chemical modification of arginine 73 residue, was performed. Biochemical and biophysical studies have shown that the modified cytochrome retains its ability to both interact and act as an electron carrier with its redox partners, ferredoxin and hydrogenase. Moreover, the chemical modification effects on the cytochrome c3 1H NMR spectrum were similar to that induced by the presence of ferredoxin. This suggests that arginine 73 is localized on the cytochrome c3 ferredoxin interacting site. The identification of heme 4, the closest heme to arginine 73, as the ferredoxin interacting heme helps us to hypothesize about the role of the three other hemes in the molecule. A structural hypothesis for an intramolecular electron transfer pathway, involving hemes 4, 3 and 1, is proposed on the basis of the crystal structures of D. vulgaris Miyazaki and D. desulfuricans Norway cytochromes c3. The unique role of some structural features (alpha helix, aromatic residues) intervening between the heme groups, is proposed.

Abstract
A single crystal of cytochrome c3 from Desulfovibrio desulfuricans Norway is studied by electron paramagnetic resonance at low temperature. The orientation of the principal axis corresponding to the largest g value is determined for the 12 heme groups in the crystal unit cell. The comparison of these directions to the normals to the heme planes, determined from the crystallographic data at 2.5 A resolution, gives strong evidence for the following assignment of the midpoint redox potentials to the heme groups H1 to H4, defined in the three-dimensional structure: -150 mV is assigned to H3, -300 mV to H4, -330 mV to H1 and -355 mV to H2. This assignment is in agreement with a partial correspondence previously established from an independent study performed on cytochrome c3 in solution.

Abstract
The soluble (cytoplasmic plus periplasmic) Ni/Fe-S/Se-containing hydrogenase from Desulfovibrio baculatus (DSM 1743) was purified from cells grown in an 57Fe-enriched medium, and its iron-sulfur centers were extensively characterized by Mössbauer and EPR spectroscopies. The data analysis excludes the presence of a [3Fe-4S] center, either in the native (as isolated) or in the hydrogen-reduced states. In the native state, the non-heme iron atoms are arranged as two diamagnetic [4Fe-4S]2+ centers. Upon reduction, these two centers exhibit distinct and unusual Mössbauer spectroscopic parameters. The centers were found to have similar mid-point potentials (approximately -315 mV) as determined by oxidation-reduction titratins followed by EPR.

Abstract
Desulfovibrio ferredoxins are small proteins involved in biological oxido-reduction reactions and contain either one or two (4Fe-4S) clusters. The conformation of D. desulfuricans Norway ferredoxin I in solution was studied by two-dimensional NMR and various conformational parameters (n.O.e. and J-coupling) indicate the presence of an alpha-helix involving residues 41 to 50. These data confirm an earlier proposal (Fukuyama et al, J. Mol. Biol. 199, 183 (1988] in which the space of the missing cluster in monocluster ferredoxins is occupied by an alpha-helix. The evolutionary relevance of this result is discussed in view of published sequences and structures of related ferredoxins.

Abstract
Cytochrome c3 (Mr 26,000) has been characterized in Desulfovibrio vulgaris (Hildenborough) and its properties compared with polyhemic cytochromes c isolated from the same organism and from D. desulfuricans (Norway). It can be described as an octaheme cytochrome c3 constituted of two identical subunits. Absorption spectrum is similar to cytochrome c3 (Mr 13,000) and individual redox potentials have an average value of -180 mV.3 The N terminal sequence is compared with an homologous cytochrome isolated from D. desulfuricans Norway.

Abstract
Three types of hydrogenases have been isolated from the sulfate-reducing bacteria of the genus Desulfovibrio. They differ in their subunit and metal compositions, physico-chemical characteristics, amino acid sequences, immunological reactivities, gene structures and their catalytic properties. Broadly, the hydrogenases can be considered as 'iron only' hydrogenases and nickel-containing hydrogenases. The iron-sulfur-containing hydrogenase ([Fe] hydrogenase) contains two ferredoxin-type (4Fe-4S) clusters and an atypical iron-sulfur center believed to be involved in the activation of H2. The [Fe] hydrogenase has the highest specific activity in the evolution and consumption of hydrogen and in the proton-deuterium exchange reaction and this enzyme is the most sensitive to CO and NO2-. It is not present in all species of Desulfovibrio. The nickel-(iron-sulfur)-containing hydrogenases [( NiFe] hydrogenases) possess two (4Fe-4S) centers and one (3Fe-xS) cluster in addition to nickel and have been found in all species of Desulfovibrio so far investigated. The redox active nickel is ligated by at least two cysteinyl thiolate residues and the [NiFe] hydrogenases are particularly resistant to inhibitors such as CO and NO2-. The genes encoding the large and small subunits of a periplasmic and a membrane-bound species of the [NiFe] hydrogenase have been cloned in Escherichia (E.) coli and sequenced. Their derived amino acid sequences exhibit a high degree of homology (70%); however, they show no obvious metal-binding sites or homology with the derived amino acid sequence of the [Fe] hydrogenase. The third class is represented by the nickel-(iron-sulfur)-selenium-containing hydrogenases [( NiFe-Se] hydrogenases) which contain nickel and selenium in equimolecular amounts plus (4Fe-4S) centers and are only found in some species of Desulfovibrio. The genes encoding the large and small subunits of the periplasmic hydrogenase from Desulfovibrio (D.) baculatus (DSM 1743) have been cloned in E. coli and sequenced. The derived amino acid sequence exhibits homology (40%) with the sequence of the [NiFe] hydrogenase and the carboxy-terminus of the gene for the large subunit contains a codon (TGA) for selenocysteine in a position homologous to a codon (TGC) for cysteine in the large subunit of the [NiFe] hydrogenase. EXAFS and EPR studies with the 77Se-enriched D. baculatus hydrogenase indicate that selenium is a ligand to nickel and suggest that the redox active nickel is ligated by at least two cysteinyl thiolate and one selenocysteine selenolate residues.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The complex formation of two electron transfer proteins, cytochrome c3 and ferredoxin I from Desulfovibrio desulfuricans Norway, has been shown by 1H-NMR spectroscopy. Presence of ferredoxin I produces ferricytochrome c3 1H-NMR spectrum modifications. The chemical shift of perturbated heme methyl resonances has been used to determine the stoichiometry of the complex. At pH 7.6 and 20 degrees C, the two proteins were found to form a complex 1:1 with an association constant, KA, of 10(4) M-1. Two of the four hemes are affected by presence of ferredoxin I and may be involved in the electron transfer sites. The heme methyl resonances are average resonances of free and bound cytochrome c3 resonances, indicating a fast exchange process on the NMR time scale.

Abstract
A soluble hydrogenase has been isolated from Desulfovibrio desulfuricans (strain Norway 4) grown on Postgate's medium. The enzyme differs significantly from a membrane-bound hydrogenase previously purified from the same organism grown on Starkey's medium. The enzyme consisted of two subunits of 56 kDa and 29 kDa compared with masses of 60 kDa and 27 kDa for the membrane-bound enzyme. Analysis of preparations of the soluble enzyme by various methods gave values of 5-10 iron atoms, 6 labile sulphur atoms and 0.45-0.8 nickel atom per molecule. The enzyme was unusual in that it contained selenium, in quantities equivalent to nickel. The highly purified active enzyme produced no electron-spin-resonance (ESR) signals in the oxidized state. ESR signals due to a [3Fe-xS] cluster and nickel were observed only in some of the less active fractions of the enzyme, demonstrating that neither of these ESR-detectable components is a prerequisite for hydrogenase activity. Treatment of D. desulfuricans (Norway) cells with EDTA released a minor fraction with hydrogenase activity, which might indicate the presence of a periplasmic enzyme.

Abstract
A c3 type cytochrome has been purified from the thermophilic, non-spore-forming, sulfate-reducing bacterium Thermodesulfobacterium commune. The purified protein was homogeneous as judged by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, gel filtration, and isoelectric focusing. A pI of 6.83 was observed. The molecular weight of the cytochrome was estimated to be ca. 13,000 from both gel filtration and sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The hemoprotein exhibited absorption maxima at 530, 408.5, and 351 nm in the oxidized form and 551.5 (alpha band), 522.5 (beta band), and 418.5 nm (gamma band) in the reduced form. The extinction coefficients of T. commune cytochrome c3 were 130,000, 74,120, and 975,000 M-1 cm-1 at 551.5, 522.5, and 418.5 nm, respectively. It contains four hemes per molecule, on the basis of both the iron estimation and the extinction coefficient value of its pyridine hemochrome. The amino acid composition showed the presence of eight cysteine residues involved in heme binding. T. commune cytochrome c3 had low threonine, serine, and glycine contents and high glutamic acid and hydrophobic residue contents. The electrochemical study of T. commune cytochrome c3 by cyclic voltammetry and differential pulse polarography has shown that the cytochrome system behaves like a reversible system. Four redox potential values at Eh1 = -0.140 +/- 0.010 V, Eh2 = Eh3 = Eh4 = -0.280 +/- 0.010 V have been determined. T. commune cytochrome c3, which acts as the physiological electron carrier of hydrogenase, is similar in most respects to the multiheme low-potential cytochrome c3 which is characteristic of the genus Desulfovibrio.

Abstract
The proton NMR spectra of the tetrahaem cytochrome c3 from Desulfovibrio gigas were examined while varying the pH and the redox potential. The analysis of the NMR reoxidation pattern was based on a model for the electron distribution between the four haems that takes into account haem-haem redox interactions. The intramolecular electron exchange is fast on the NMR time scale (larger than 10(5) s-1). The NMR data concerning the pH dependence of the chemical shift of haem methyl resonances in different oxidation steps and resonance intensities are not compatible with a non-interacting model and can be explained assuming a redox interaction between the haems. A complete analysis at pH* = 7.2 and 9.6, shows that the haem-haem interacting potentials cover a range from -50 mV to +60 mV. The midpoint redox potentials of some of the haems, as well as some of their interacting potentials, are pH-dependent. The physiological relevance of the modulation of the haem midpoint redox potentials by both the pH and the redox potential of the solution is discussed.

Abstract
Desulfovibrio gigas ferredoxin II (FdII) contains a single 3Fe cluster [Huynh, B.H., Moura, J.J.G., Moura, I., Kent, T.A., LeGall, J., Xavier, A.V., and Münck, E. (1980) J. Biol. Chem. 255, 3242-3244]. In the oxidized state the protein exhibits an intense electron paramagnetic resonance (EPR) signal at g = 2.02. Upon one-electron reduction the center becomes EPR silent. In the presence of D. gigas crude cell extracts, devoid of acidic electron carriers and supplemented with pyruvate and FdII, an EPR signal typical of reduced [4Fe-4S] centers is obtained. The appearance of this signal correlates with the beginning of stimulation of the phosphoroclastic reaction as judged by the production of H2. These results, supported by the occurrence of easy chemical conversion of the 3Fe cluster of D. gigas ferredoxin into 4Fe structures [Moura, J.J.G., Moura, I., Kent, T.A., Lipscomb, J.D., Huynh, B.H., LeGall, J., Xavier, A.V., and Münch, E. (1982) J. Biol. Chem. 257, 6259-6267], suggest that cluster conversion takes place in conditions close to the situation in vivo. This cluster interconversion is discussed in the context of some of the relevant metabolic pathways of Desulfovibrio spp.

Abstract
Ferredoxin, cytochrome c3 and hydrogenase are specific partners of the sulfate reduction pathway of Desulfovibrio desulfuricans Norway and might be exemplary for electron exchange mechanism studies. Cytochrome c3 contains four low redox potential haems for 13 000 molecular weight. Two ferredoxins isolated from the same bacteria are dimers of 6 000 molecular weight per subunit (Ferredoxin I: one (4 Fe-4S) cluster per subunit, ferredoxin II: two (4 Fe-4 S) clusters per subunit). The amino acid sequence of ferredoxin I is reported and compared to the ferredoxin II sequence. The structural characteristics of ferredoxins and cytochrome c3 should allow a discussion on the nature of the interaction. 1H-NMR spectra of ferredoxin I and cytochrome c3 in the absence and presence of ferredoxin are presented.

Abstract
Redox properties of cytochrome c553(550) from Desulfovibrio desulfuricans Norway (Eo' = 0.04 + 0.02 V/NHE) and cytochrome c551 from P. aeruginosa (Eo = 0.25 +/- 0.02 V/NHE) are compared with those of some monohemic c-type cytochromes. The pK value for the equilibrium between the pH-dependent forms of cytochrome c553(550) (pK = 10.3 +/- 0.1) has been also determined. It is to be noted that the difference between redox potentials can extend to nearly 250 mV, though the axial heme ligands are identical. Structural reasons have to be invoked to explain these variations.

Abstract
Hydrogenase of Desulfovibrio vulgaris shows nonlinear kinetics in hydrogen production with both the natural electron carrier, cytochrome c3, and the artificial donor, methyl viologen semiquinone. Increasing concentrations of salt progressively inhibit the hydrogen production, as do increasing amounts of dimethylsulfoxide (Me2SO). Hydrogen consumption activity does not change up to 30% (v/v) of Me2SO. Preincubation in Me2SO up to 55% (v/v) does not affect the hydrogen uptake or production. The production activity of the enzyme shows an optimum around pH 6. When plotted as a function of redox potential the activity can be fitted to a Nernst equation with n = 1. Midpoint potentials calculated at various values follow approximately the hydrogen electrode to pH 6. Thereafter, there is a shift of about 40 mV to higher redox potentials.

Abstract
The primary structure of a ferredoxin isolated from D. desulfuricans Norway strain, which we called ferredoxin II (Fd II) has been elucidated. This ferredoxin is a dimer constituted of two identical subunits of molecular weight 6000. In ferredoxin II two (4 Fe-4 S) centers are present per subunit instead of one (Fe-S) center as is the case for the other ferredoxins isolated from Desulfovibrio and for Fd I from the same organism. The comparison of amino-acid sequences shows that ferredoxin II presents more homologies with clostridial type ferredoxin than with the ferredoxins from D. gigas and D. africanus.

Abstract
Three different ferredoxins have been isolated from the sulfate reducing bacterium, Desulfovibrio africanus. The present paper describes the complete amino acid sequence of D. africanus ferredoxin I. This sequence was determined using automatic protein sequencing in liquid phase and in solid phase. The 61 amino acid residues of the sequence have been aligned with the aid of peptides obtained by cyanogen bromide, cleavage and by tryptic hydrolysis. This ferredoxin which contains 4 cysteine residues represents the most simple case of one (4 Fe-4 S) cluster ferredoxin. A comparison of D. africanus ferredoxin I with D. gigas and Clostridium pasteurianum ferredoxins is presented in terms of structural and possible evolutionary relationships.

Abstract
Two ferredoxins from Desulfovibrio desulfuricans, Norway Strain, were investigated by EPR spectroscopy. Ferredoxin I appears to be a conventional [4Fe-4S]2+;1+ ferredoxin, with a midpoint reduction potential of -374 mV at pH 8. Ferredoxin II when reduced, at first showed a more complex spectrum, indicating an interaction between two [4Fe-4S] clusters, and probably, has two clusters per protein subunit. Upon reductive titration ferredoxin II changed to give a spectrum in which no intercluster interaction was seen. The midpoint potentials of the native and modified ferredoxin at pH 8 were estimated to be -500 and -440 mV, respectively.
