The membrane-bound C subunit of reductive dehalogenases: topology analysis and reconstitution of the FMN-binding domain of PceC

Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Géraldine Florence Buttet, Aamani Rupakula Boyanapalli

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 ...

RdhC, a family of membrane-bound flavoproteins involved in electron transfer in organohalide respiration ?

Julien Maillard, Romain Hamelin, Mathilde Stéphanie Willemin, Géraldine Florence Buttet

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 ...

Properties of Enzymes Involved in Tetrachloroethene Respiration

Géraldine Florence Buttet

Tetrachloroethene (PCE) pollution threatens nature and human health due to its toxic and carcinogenic potential. Due to industrial activities, large amounts of PCE were discharged into the environment over the last decades and represent one of major ground ...

Dehalobacter – a genus of anaerobic bacteria dedicated to organohalide degradation

Christof Holliger, Julien Maillard

Abstract The genus Dehalobacter embraces bacterial populations that seem to exclusively degrade organohalides. All isolates in pure culture and highly enriched strains are obligate organohalide-respiring bacteria that use hydrogen as energy and electron so ...

A molecular chaperone dedicated to folding and translocation of reductive dehalogenases

Julien Maillard, Corantin Grob

Reductive dehalogenases (rdhA, RDases) are key enzymes involved in anaerobic organohalide respiration (OHR), during which bacteria are able to use chlorinated compounds as terminal electron acceptors. RDases are redox enzymes containing FeS clusters and a ...

Functional diversity of reductive dehalogenases in a bacterial consortium degrading chloroethenes

Christof Holliger, Julien Maillard, Géraldine Florence Buttet, Sébastien Keller

Chlorinated hydrocarbon pollution threatens nature and human health due to its toxic and carcinogenic potential. Enrichment cultures were investigated for the bioremediation potential of tetrachloroethene (PCE). This process is based on bacterial anaerobic ...

Do crosstalks with primary and secondary metabolism limit or stimulate the detoxification of xenobiotics?

Jean-Paul Schwitzguebel

Because plants are static and live in a competitive and sometimes hostile environment, they have evolved efficient mechanisms that protect them from abiotic and biotic stresses. These mechanisms include detoxification and sequestration of xenobiotic compou ...

On-site biostimulation evaluation of a remediated perchloroethene-contaminated acquifer located in Jablunkov, Czech Republic

Isabelle Fäh

Chlorinated ethenes solvents (CEs) are one of the most common contaminants identified in groundwater ecosystems. Long used as a degreaser in industry, perchloroethene (PCE) and trichloroethene (TCE) are particularly persistent in the environment as recalci ...
