Microbially-mediated halogenation and dehalogenation cycling of organohalides in the ocean [PDF]

Nature Communications
Microbially mediated organohalide cycling in the ocean has profound implications for global biogeochemical cycles and climate, but the geographic distribution and diversity of the halogenation-dehalogenation cycling microorganisms remain unknown.

Reductive dechlorination of tetrachloroethene by a stepwise catalysis of different organohalide respiring bacteria and reductive dehalogenases [PDF]

Biodegradation, 2018
The enrichment culture SL2 dechlorinating tetrachloroethene (PCE) to ethene with strong trichloroethene (TCE) accumulation prior to cis-1,2-dichloroethene (cis-DCE) formation was analyzed for the presence of organohalide respiring bacteria and reductive ...

Efficient NADPH-dependent dehalogenation afforded by a self-sufficient reductive dehalogenase. [PDF]

J Biol Chem, 2023
Reductive dehalogenases are corrinoid and iron-sulfur cluster-containing enzymes that catalyze the reductive removal of a halogen atom. The oxygen-sensitive and membrane-associated nature of the respiratory reductive dehalogenases has hindered their detailed kinetic study.

Genome-resolved transcriptomics reveals novel PCE-dehalogenating bacteria from Aarhus Bay sediments [PDF]

mSystems
Organohalide-respiring bacteria (OHRB) are keystone microbes in bioremediation of sites contaminated with organohalides and in natural halogen cycling.

Comparative proteogenomics reveals ecological and evolutionary insights into the organohalide-respiring Dehalobacter restrictus strain T [PDF]

Applied and Environmental Microbiology
1,1,1-Trichloroethane (1,1,1-TCA) and chloroform (CF) are persistent groundwater contaminants because of their widespread industrial use as organic solvents and improper disposal in the past.

Regulation of reductive dehalogenase gene transcription in Dehalococcoides mccartyi. [PDF]

Philos Trans R Soc Lond B Biol Sci, 2013
The remarkable capacity of the genus Dehalococcoides to dechlorinate a multitude of different chlorinated organic compounds reflects the number and diversity of genes in the genomes of Dehalococcoides species encoding reductive dehalogenase homologues ( rdh ).

Reductive dehalogenase structure suggests a mechanism for B12-dependent dehalogenation. [PDF]

Nature, 2015
Organohalide chemistry underpins many industrial and agricultural processes, and a large proportion of environmental pollutants are organohalides. Nevertheless, organohalide chemistry is not exclusively of anthropogenic origin, with natural abiotic and biological processes contributing to the global halide cycle. Reductive dehalogenases are responsible

Dehalococcoides mccartyi strain CBDB1 takes up protons from the cytoplasm to reductively dehalogenate organohalides indicating a new modus of proton motive force generation

Frontiers in Microbiology, 2023
Proton translocation across the cytoplasmic membrane is a vital process for all organisms. Dehalococcoides strains are strictly anaerobic organohalide respiring bacteria that lack quinones and cytochromes but express a large membrane-bound protein ...
