Organohalide respiration potential in marine sediments from Aarhus Bay [PDF]
FEMS Microbiology Ecology, 2022 Abstract Organohalide respiration (OHR), catalysed by reductive dehalogenases (RDases), plays an important role in halogen cycling. Natural organohalides and putative RDase-encoding genes have been reported in Aarhus Bay sediments, however, OHR has not been experimentally verified.

Organohalide respiration: microbes breathing chlorinated molecules [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 Bacterial respiration has taken advantage of almost every redox couple present in the environment. The reduction of organohalide compounds to release the reduced halide ion drives energy production in organohalide respiring bacteria. This process is centred around the reductive dehalogenases, an iron–sulfur and corrinoid containing family of enzymes ...

From Energy Deprivation Stress to Catalytic Adaptation of Reductive Dehalogenase TmrA for 1,1-DCA Dechlorination: An Experimental and in Silico Study. [PDF]
Microb BiotechnolAdaptive evolution of Dehalobacter restrictus strain UNSWDHB under a ratio of 1:9 chloroform:1,1‐DCA regime increased 1,1‐DCA dechlorination. Sequencing and molecular dynamics simulation reveal high‐entropy tmrA mutations that improved 1,1‐DCA binding energy and stabilize the catalytic pocket, outlining a route to tune reductive dehalogenases for ...
