Mimicking reductive dehalogenases for efficient electrocatalytic water dechlorination
Nature Communications, 2023 AbstractElectrochemical technology is a robust approach to removing toxic and persistent chlorinated organic pollutants from water; however, it remains a challenge to design electrocatalysts with high activity and selectivity as elaborately as natural reductive dehalogenases.

[4Fe-4S]-mediated proton-coupled electron transfer enables the efficient degradation of chloroalkenes by reductive dehalogenases [PDF]
, 2022 Reductive dehalogenases (RDases) are key enzymes involved in the degradation of organohalide compounds. Despite extensive experi-mental and computational studies, the catalytic mechanism of RDases remains unclear. We show here that the proximal [4Fe-4S]1+

Identification of a reductive tetrachloroethene dehalogenase in Shewanella sediminis [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2013 The genome sequence of psychrophilic Shewanella sediminis revealed the presence of five putative reductive dehalogenases (Rdhs). We found that cell extracts of pyruvate/fumarate-grown S.

Guided cobamide biosynthesis for heterologous production of reductive dehalogenases [PDF]
Microbial Biotechnology, 2018 Summary Cobamides (Cbas) are essential cofactors of reductive dehalogenases (RDases) in organohalide‐respiring bacteria (OHRB). Changes in the Cba structure can influence RDase function. Here, we report on the cofactor versatility or selectivity of Desulfitobacterium RDases ...

Purinyl-cobamide is a native prosthetic group of reductive dehalogenases [PDF]
Nature Chemical Biology, 2017 Cobamides such as vitamin B12 are structurally conserved, cobalt-containing tetrapyrrole biomolecules that have essential biochemical functions in all domains of life. In organohalide respiration, a vital biological process for the global cycling of natural and anthropogenic organohalogens, cobamides are the requisite prosthetic groups for carbon ...

Bioremediation of halogenated compounds: comparison of dehalogenating bacteria and improvement of catalyst stability [PDF]
, 2006 Five bacterial strains were compared for halogenated compounds conversion in aqueous media. Depending on the strain, the optimal temperature for dehalogenase activity of resting cells varied from 30 to 45 degrees C, while optimal pH raised from 8.4 to 9 ...

Characterization of tetrachlorohydroquinone reductive dehalogenase from Sphingomonas sp. UG30 [PDF]
Biochemical and Biophysical Research Communications, 2002 Tetrachlorohydroquinone reductive dehalogenase (PcpC) is the second of three enzymes that catalyze the initial degradation of pentachlorophenol in Sphingomonas sp. UG30 and several other bacterial strains. The UG30 PcpC shares a high degree (94%) of primary sequence identity with the well-studied PcpC from Sphingobium chlorophenolicum ATCC 39723 ...
