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

open access: yesCommunications 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

The Membrane-Bound C Subunit of Reductive Dehalogenases: Topology Analysis and Reconstitution of the FMN-Binding Domain of PceC

open access: yesFrontiers in Microbiology, 2018
Organohalide respiration (OHR) is the energy metabolism of anaerobic bacteria able to use halogenated organic compounds as terminal electron acceptors.

Environmental considerations and bioremediation applications of the metal-, nitrate-, and organohalide-respiring bacterium Trichlorobacter lovleyi (formerly Geobacter lovleyi)

open access: yesApplied and Environmental Microbiology
Trichlorobacter lovleyi (formerly Geobacter lovleyi) is a gram-negative bacterium that can couple the oxidation of acetate or other small organic acids with the reduction of soluble and insoluble electron acceptors, such as chlorinated solvents, heavy ...

Chlorine Isotope Effects from Isotope Ratio Mass Spectrometry Suggest Intramolecular C-Cl Bond Competition in Trichloroethene (TCE) Reductive Dehalogenation

open access: yesMolecules, 2014
Chlorinated ethenes are prevalent groundwater contaminants. To better constrain (bio)chemical reaction mechanisms of reductive dechlorination, the position-specificity of reductive trichloroethene (TCE) dehalogenation was investigated.

Diversity of reductive dehalogenase genes from environmental samples and enrichment cultures identified with degenerate primer PCR screens.

open access: yesFrontiers in Microbiology, 2013
Reductive dehalogenases are the critical enzymes for anaerobic organohalide respiration, a microbial metabolic process that has been harnessed for bioremediation efforts to resolve chlorinated solvent contamination in groundwater and is implicated in the

Kinetics and Threshold Level of 2,3,4,5-Tetrachlorobiphenyl Dechlorination by an Organohalide Respiring Bacterium

open access: yesEnvironmental Science & Technology, 2014
The time required for a PCB-contaminated site to recover cannot yet be predicted due in part to lack of quantitative information on rates of PCB dechlorination in the porewater phase. We developed a method to measure rate of dechlorination in the aqueous phase at very low PCB concentrations.

Organohalide respiration in Firmicutes: energy metabolism and transcription regulation

open access: yes, 2021
Organohalides are a class of compounds often considered as persistent pollutants and harmful to environmental and human health. Some bacteria, among which are representatives from the Firmicutes phylum, are capable of using these compounds as terminal acceptors in a process called organohalide respiration (OHR).

Ecophysiology and environmental distribution of organohalide-respiring bacteria

open access: yes, 2016
Organohalide-respiring bacteria (OHRB) are able to breathe natural and anthropogenically produced organohalides persistent in a broad range of oxygen-depleted environments. Therefore, these microorganisms are of high interest for organohalide-contaminated site bioremediation and natural halogen and carbon cycle.
