Tetrachloroethene reductive dehalogenase

UniProtKB accession:  O68252

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Catalyzes the reductive dechlorination of tetrachloroethene (PCE) to trichloroethene (TCE) and of trichloroethene to cis-1,2-dichloroethene (DCE) (PubMed:11976751, PubMed:12420164, PubMed:24433392, PubMed:28671181, PubMed:8663199). In addition, trans-1,3-dichloropropene, 1,1,3-trichloropropene and 2,3-dichloropropene are reduced to a mixture of mono-chloropropenes, 1,1-dichloropropene, and 2-chloropropene, respectively (PubMed:11976751). Is also able to convert brominated phenols such as 4-bromophenol (4-BP), 2,4-dibromophenol (2,4-DBP) and 2,4,6-tribromophenol (2,4,6-TBP) (PubMed:28671181). Utilizes formate or pyruvate as electron donors (PubMed:16802174, PubMed:24433392). Titanium(III) citrate could also serve as electron donor (PubMed:11976751). Reduced methyl viologen can act as the artificial electron donor (PubMed:11976751, PubMed:12420164, PubMed:8663199).
