Cofactor binding interactions with reductive dehalogenase shape cobamide utilization in organohalide-respiring bacteria [PDF]

Communications Biology
Selective utilization of certain cobamides, the vitamin B12-family enzyme cofactors, is a common physiological trait in organohalide respiration, an essential biogeochemical process relevant to global halogen cycling and the bioremediation of chlorinated

Characterization of the corrinoid iron-sulfur protein tetrachloroethene reductive dehalogenase of Dehalobacter restrictus [PDF]

Applied and Environmental Microbiology, 2003
The membrane-bound tetrachloroethene reductive dehalogenase (PCE-RDase) (PceA; EC 1.97.1.8), the terminal component of the respiratory chain of Dehalobacter restrictus, was purified 25-fold to apparent electrophoretic homogeneity.

Isolation and Characterization of Dehalobacter sp. Strain TeCB1 Including Identification of TcbA: A Novel Tetra- and Trichlorobenzene Reductive Dehalogenase [PDF]

Front Microbiol, 2017
Dehalobacter sp. strain TeCB1 was isolated from groundwater near Sydney, Australia, that is polluted with a range of organochlorines. The isolated strain is able to grow by reductive dechlorination of 1,2,4,5-tetrachlorobenzene to 1,3- and 1,4 ...

Organohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation

Frontiers in Microbiology, 2016
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use ...

Comparative genomics reveals Dehalogenimonas genome dynamics and evolutionary trajectories toward organohalide respiration [PDF]

Applied and Environmental Microbiology
Dehalogenimonas spp. specialize in organohalide respiration, a metabolism that features reductive dehalogenase (RDase) as the key catalyst, yet their evolutionary history and adaptation to halogenated substrates are largely unknown. Here, we surveyed the
