Anaerobic Biodegradation of organohalide pollutants: a crucial step towards the elucidation of proteins involved

Christof Holliger, Julien Maillard, Adrian Schmid, Lorenzo Cimmino

Halogenated organic compounds (so-called organohalides) represent one of the major class of groundwater pollutants. The exploration of how organohalides are used as energy source is important in terms of ecosystem remediation but is also essential for the ...

Integral and peripheral membrane proteins account for one-third of the human proteome, and they are estimated to represent the target for over 50% of modern medicinal drugs. Despite their central role in medicine, the complex, heterogeneous and dynamic nat ...

Organohalide respiration (OHR) is a bacterial anaerobic respiratory process in which halogenated compounds are used as terminal electron acceptors. Desulfitobacterium and Dehalobacter, paradigmatic organohalide-respiring bacteria (OHRB), harbour the pceABC ...

Abstract Background The NADH:ubiquinone oxidoreductase (Nuo) is an assembly of proteins also known as complex I. It is the entry point for highly energetic electrons in the classical aerobic respiration process as it couples the transfer of two electrons f ...

Organohalide respiration (OHR) is an anaerobic metabolism by which bacteria conserve energy with the use of halogenated compounds as terminal electron acceptors. Genes involved in OHR are organized in reductive dehalogenase (rdh) gene clusters and can be f ...

Organohalide respiration (OHR) is a bacterial energy metabolism making use of halogenated compounds – like tetrachloroethene (PCE), a major pollutant – as terminal electron acceptors. Three models of electron transport chain exist for OHR [1], however many ...

Organohalide respiration (OHR) is the energy metabolism of anaerobic bacteria able to use halogenated organic compounds as terminal electron acceptors. While the terminal enzymes in OHR, so-called reductive dehalogenases, are well-characterized, the identi ...

Characterization of the predicted membrane anchor of reductive dehalogenases

Julien Maillard, Lorenzo Cimmino, Marie Joanna Marie-Joseph Dannay

BACKGROUND Organohalide respiration (OHR) is a metabolic process that couples the reduction of halogenated organic compounds to energy conservation in a few phylogenetically diverse anaerobic bacteria. In this study, tetrachloroethene (= perchloroethene, P ...

Protocols for Subtomogram Averaging of Membrane Proteins in the Dynamo Software Package

Henning Paul-Julius Stahlberg

Cryo-electron tomography allows low-resolution three-dimensional (3D) viewing of cellular organelles and macromolecular complexes present as multiple copies within a tomogram. These structures are computationally extracted and averaged in order to obtain h ...
