Activités de recherche :
Elles s’articulent autour de 2 axes :
– l’étude d’enzymes rédox membranaires et leur rôle dans le métabolisme énergétique global des bactéries (métabolisme H2, Soufre , O2 chez la bactérie environnementale Aquifex aeolicus) pour comprendre les stratégies énergétiques mises en place en réponse aux changements environnementaux (comme la concentration en O2 ou la nature de la source d’énergie).
– l’étude des interactions physiologiques et métaboliques des bactéries au sein d’un consortium (ex : Desulfovibrio vulgaris et Clostridium acetobutylicum)
Pour mener à bien ces projets, j’utilise une approche pluridisciplinaire et je m’emploie au développement de protocoles de purification (protéines solubles et membranaires), de techniques de mesures des métabolites et des outils qui leur sont associés (AkTA et HPLC).
Compétences en biochimie des protéines membranaires et des quinones :
Purification de protéines, complexes et supercomplexes protéiques solubles et membranaires rédox natifs
-Mise au point des protocoles de purification
Protéines : Techniques de chromatographie basse pression et,FPLC
Quinones : Techniques sur plaques TLC
– Caractérisation biochimique
Séparation des protéines sur gradient de sédimentation (sucrose, PEG)
Séparation des protéines sur gels d’électrophorèse (type Blue Native (BN), Clear native (CN), gels 2D), approches protéomiques, expériences d’immunoblots
– Caractérisation et Reconstitution de voies métaboliques (in vitro), mesures de flux (in vivo)
Spectroscopie UV/visible
Enzymologie (Mise au point de tests, cinétique, effecteurs)
