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 ...

A common mechanism for coenzyme cobalamin-dependent reductive dehalogenases
Phys. Chem. Chem. Phys., 2017 Distinct mechanisms have been proposed for the biological dehalogenation catalyzed by cobalamin-dependent enzymes, with two recent crystallographic studies suggesting different mechanisms based on the observed interaction between the organohalide substrate and cobalamin.

Multiple Dual C−Cl Isotope Patterns Associated with Reductive Dechlorination of Tetrachloroethene [PDF]
, 2017 Dual isotope slopes are increasingly used to identify transformation pathways of contaminants. We investigated if reductive dechlorination of tetrachloroethene (PCE) by consortia containing bacteria with different reductive dehalogenases (rdhA) genes can

Production of Functional Recombinant Chloroform Reductive Dehalogenase
, 2021 Organohalides are recalcitrant, toxic environmental pollutants. The presence of these compounds at elevated levels in soil and aquifers has led to a focus on methods to remediate these sites. Reductive dehalogenase enzymes (RDases) found in organohalide respiring bacteria (OHRB) utilise organohalides as electron acceptors for cellular energy and growth,

Functional Expression and Characterization of Tetrachloroethene Dehalogenase From Geobacter sp.
Frontiers in Microbiology, 2018 Reductive dehalogenase (RDase) consists of two parts, RdhA and RdhB. RdhA is the catalytic subunit, harboring a cobalamin cofactor and two Fe–S clusters. RdhA is anchored to the cytoplasmic membrane via the membrane anchoring subunit, RdhB.

Genomic Characteristics Distinguish Geographically Distributed Dehalococcoidia
Frontiers in Microbiology, 2020 Dehalococcoidia (Dia) class microorganisms are frequently found in various pristine and contaminated environments. Metagenome-assembled genomes (MAGs) and single-cell amplified genomes (SAGs) studies have substantially improved the understanding of Dia ...
