| Abstract | BIOSIS COPYRIGHT: BIOL ABS. The bacterial transition-metal coenzymes vitamin B12 (Co), coenzyme F430 (Ni), and hematin (Fe) catalyzed the reductive dechlorination of polychlorinated ethylene and benzenes, whereas the electron-transfer proteins four-iron ferredoxin, two-iron ferredoxin, and azurin (Cu) did not. For vitamin B12 and coenzyme F430, reductive dechlorination rates for different classes of perchlorinated compounds had the following order: carbon tetrachloride tetrachloroethylene hexachlorobenzene. For hematin, the order of reductive dechlorination rates was carbon tetrachloride hexachlorobenzene tetrachloroethylene. Within each class of compounds, rates of dechlorination decreased with decreasing chlorine content. Regio- and stereospecificity were observed in these reactions. In the reductive dechlorination of trichloroethylene, cis-1,2-dichloroethylene was the predominant product formed with vitamin B12, coenzyme F430, and hematin. Pentachlorobenzene and pentachloroph |
