Characterization of tetrachlorohydroquinone reductive dehalogenase from Sphingomonas sp. UG30 [PDF]
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 ...

Mimicking reductive dehalogenases for efficient electrocatalytic water dechlorination
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.

Guided cobamide biosynthesis for heterologous production of reductive dehalogenases [PDF]
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 ...

GENETICS AND BIOCHEMISTRY OF DEHALOGENATING ENZYMES [PDF]
Microorganisms that can utilize halogenated compounds as a growth substrate generally produce enzymes whose function is carbon-halogen bond cleavage. Based on substrate range, reaction type and gene sequences, the dehalogenating enzymes can be classified

Divergent roles of CprK paralogues from Desulfitobacterium hafniense in activating gene expression [PDF]
Gene duplication and horizontal gene transfer play an important role in the evolution of prokaryotic genomes. We have investigated the role of three CprK paralogues from the cAMP receptor protein-fumarate and nitrate reduction regulator (CRP-FNR) family ...

Functional Heterologous Production of Reductive Dehalogenases from Desulfitobacterium hafniense Strains [PDF]
ABSTRACT The anaerobic dehalogenation of organohalides is catalyzed by the reductive dehalogenase (RdhA) enzymes produced in phylogenetically diverse bacteria. These enzymes contain a cobamide cofactor at the active site and two iron-sulfur clusters.

Reductive dehalogenation has been found primarily in anaerobic communities and is originally thought to rarely occur in aerobes. A reductive dehalogenase (BhbA) was characterized from an aerobic strain of Comamonas sp.
