Abstract:
Electron transferring metalloproteins are typically implicated in shuttling electrons between energy transduction chains membrane complexes, such as in (aerobic and anaerobic) respiration and photosynthesis, among other functions. The thermodynamic and kinetic electron transfer parameters of the different metalloproteins need to be adjusted in each case to the specific demands, which can be quite diverse among organisms. Notably, biology utilizes very few metals, essentially iron and copper, to cover this broad range of redox needs imposed by biodiversity. Here, I will describe some crucial structural and dynamical characteristics that modulate the electron transfer parameters (and alternative functions) of two prototypical metalloproteins: the iron protein cytochrome c and its redox partner, the CuA center of the terminal respiratory enzyme cytochrome c oxidase. Specifically, I will focus on summarizing results obtained in recent years in my laboratory.

Abstract:
Metalloproteins and enzymes are an essential part of all respiratory electron-transfer chains and provide a pathway for electron transfer to terminal electron acceptors. Since bacteria can utilize a wide range of respiratory substrates, this variety of potential electron acceptors has facilitated the need for many different respiratory metalloproteins. Bacterial selenate respiration requires the sequential reduction of the selenium oxyanions selenate and selenite resulting in the precipitation of elemental selenium. The initial bioenergetic processes of selenate respiration are driven by metalloproteins utilizing cofactors containing iron and molybdenum. However, the assembly of the elemental selenium into selenium nanosphere crystals has shed light on a new family of proteins involved in selenium biomineralization. This article highlights some of the recent advances in our understanding of selenate respiration in the bacterium Thauera selenatis, with particular focus on the metalloproteins involved in selenate reduction and the novel proteins that function to deal with these insoluble selenium deposits. “As mineralogy constitutes a part of chemistry, it is clear that this arrangement of minerals must derive its principles from chemistry” Jöns Jacob Berzelius 1814

Abstract:
The metal chromophore in metalloproteins is identified as a high affinity site for dry electrons in conformity with previous studies. Relative electron affinities for such centres in a physiologically probable valence hybrid haemoglobin have been determined. A ratio of ca. 2.5 for the electron affinity of oxyhaemog1obin over methaemog1obin is explained in terms of structural differences in the constituent forms. The phenomenon of intersubunit electron transfer in similar systems is considered in terms of haem edge-to-edge minimum separation. The hydrogen peroxide complex of iron haemoproteins is characterised as an oxo compound of iron in the +4 oxidation state (ferryl), by electronic spectroscopy and ESR spectroscopy using low temperature ?-irradiation. Variations in ESR parameters during annealing are explained in terms of structural changes at the haem site. The electron-loss centre in many proteins, consequent upon ?-irradiation, is identified as the polypeptide amide nitrogen. The nitrogen-centred radical first formed may undergo hydrogen transfer reactions to give a terminal carbon-centred radical. ESR features for the nitrogen-centred radical are interpreted in relation to predominant secondary structures in the proteins examined. The catalytic mechanism of xanthine oxidase has been studied by the use of dry electrons as the reducing substrate. The series of intermediates obtained through annealing have ESR parameters identical with those for the enzyme-substrate intermediates obtained by other workers using chemical reducing substrates. A scheme of intramolecular electron transfer is proposed.

Abstract:
Acidithiobacillus ferrooxidans (A. f.) est un modèle bactérien parfaitement adapté à l’étude de la survie en milieu acide. Si plusieurs métalloprotéines ont été identifiées et caractérisées d’un point de vue biochimique, le fonctionnement de la chaîne respiratoire couplant l’oxydation du Fe(II) à la réduction de l’oxygène dans cet organisme n’est pas élucidée. Au cours de ce travail de thèse, après avoir optimisé les conditions de croissance de la bactérie et de production des protéines redox impliquées, nous avons reconstitué sur interface électrochimique une partie de la chaîne respiratoire d’A. f. dans le but de déterminer étape par étape le chemin de transfert d’électrons (TE). Notre attention s’est portée sur trois protéines qui interagissent dans la chaîne respiratoire: la cytochrome c oxidase (CcO), la cuprédoxine AcoP, qui copurifie avec la CcO mais de fonction inconnue, et un cytochrome dihémique (Cyt c4) proposé comme interagissant avec la CcO. La mise en évidence, puis la quantification d’un TE intermoléculaire entre le Cyt c4 et AcoP, puis entre le Cyt c4 et la CcO nous a permis de proposer un rôle pour AcoP et un nouveau chemin de TE vers la CcO. Nous avons ensuite étudié les propriétés électrochimiques de la CcO vis à vis de la réduction catalytique de l’O2, en particulier avec une forte affinité. Nous avons ainsi pu montrer que la CcO de A. f. réduisait l’O2 à des potentiels 500 mV plus anodiques que les CcO neutrophiles par une connexion directe de l’enzyme sur nanomatériaux carbonés. Affinité pour O2 et haut potentiel redox font de cette CcO une enzyme de choix pour développer une nouvelle génération de piles à combustible enzymatique<br>Acidithiobacillus ferrooxidans is one of the most studied bacterial models to understand how to survive in an acid environment. Although several metalloproteins have been identified and characterized from a biochemical point of view, the electron transfer pathway (ET) of the respiratory chain coupling the oxidation of ferrous iron with the reduction of oxygen in this organism has not been elucidated.During this thesis work, after having optimized the growth conditions of the bacterium and the production of the redox proteins involved, we reconstituted on the electrochemical interface part of the respiratory chain of A. ferrooxidans for the purpose of determining step by step the ET. Our attention focused on three proteins that interact in the respiratory chain: cytochrome c oxidase (CcO), the cupredoxin AcoP, which co-purifies with CcO but of unknown function, and a cytochrome dihemic (Cyt c4) proposed as interacting with the CcO. The demonstration, then the quantification of an intermolecular ET between the Cyt c4 and AcoP, then between the Cyt c4 and the CcO allowed us to propose a role for AcoP and a new pathway for the ET to the CcO. We then studied the electrochemical properties of CcO with respect to the catalytic reduction of O2. We have demonstrated the strong affinity of this oxidase for O2. We have established the chemical functions required to obtain a direct wiring of the enzyme on carbon nanomaterials. This showed that A. ferrooxidans CcO reduced O2 at potentials 500 mV more anodic than neutrophilic CcOs. Affinity for O2 and high redox potential make this CcO an enzyme of choice to develop a new generation of enzymatic fuel cells

Abstract:
Les ferredoxines a 4fe-4s constituent une categorie de metalloproteines particulierement etudiee depuis leur decouverte dans les annees 1960 en raison de leur fonction clef de transfert electronique dans les metabolismes essentiels de la vie. Le cluster de type pseudo-cubane 4fe-4s opere entre les deux etats redox fe#4s#4#2#+(2+) et fe#4s#4#1#+(1+) et est responsable du transfert electronique. Il est possible d'en synthetiser chimiquement des analogues afin d'en simplifier l'etude. Ses proprietes magnetiques font l'objet de beaucoup d'investigations car il presente des couplages magnetiques complexes entre les spins des atomes de fer, couplages que nous avons etudies ici par rmn en solide. Dans cette these, les (cinq) complexes modeles synthetises et etudies sont ceux ayant pour ligands, soit le tertiobutylthiolate, soit le benzylthiolate deuterie et enrichi selectivement en #1#3c. Nous avons etudie ces clusters 4fe-4s dans les deux etats redox (2+) et (1+) par rmn du #1#3c en solide en fonction de la temperature (de 180 a 330 k). Nous avons en particulier mene des experiences de rmn bidimensionnelle en solide correlant deplacements chimiques isotropes et anisotropes. Pour interpreter les courbes de dependance en temperature obtenues, nous avons eu recours a differents modeles de couplage magnetique. Dans le cas des composes reduits d'etat redox (1+), nous avons ete conduit a elaborer un nouveau modele mettant en evidence la necessite d'une delocalisation differenciee des electrons de valence sur les quatre sites de fer. Dans ce cas, l'analyse de ces courbes s'est averee particulierement interessante puisque la rmn en solide du #1#3c, qui introduit des sondes locales de la distribution de la densite de spin dans le cluster, apporte une richesse d'information beaucoup plus contraignante a l'egard des modeles que la susceptometrie. La rmn en solide apparait donc comme une technique de choix pour ce type d'analyse.
