Degradation of polychlorinated biphenyl metabolites by naphthalene-catabolizing enzymes

A study was conducted to examine the capability of the dehydrogenase and ring cleavage dioxygenase of the naphthalene degradation pathway to change 3,4-dihydroxylated biphenyl metabolites. Escherichia coli M15(pREP4) and SG13009 were utilized as bacterial strains while protein characterization was carried out using sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Results indicated that the recruitment of catabolic enzymes supporting specificities supporting enzymes of the biphenyl degradation pathway may lead to the degradation of polychlorinated biphenyls.
