Degradation of Polychlorinated Biphenyl Metabolites by Naphthalene-Catabolizing Enzymes [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT The ability of the dehydrogenase and ring cleavage dioxygenase of the naphthalene degradation pathway to transform 3,4-dihydroxylated biphenyl metabolites was investigated. 1,2-Dihydro-1,2-dihydroxynaphthalene dehydrogenase was expressed as a histidine-tagged protein.

Polychlorinated naphthalenes in the serum of individuals with thyroid dysfunction and their potential mechanisms of impact on disease progression

Emerging Contaminants
Polychlorinated naphthalenes (PCNs) comprise 75 congeners, with varying concentrations and major congeners across different populations. Recent studies have found a relationship between PCNs and thyroid hormone levels, suggesting they may interfere with ...
