Biochem Pharmacol. 2006 May 28;71(11):1629-36. Epub 2006 Apr 18.

2, 3, 5, 6-Tetrachloro-1, 4-benzoquinone (TCBQ) is a metabolite of pentachlorophenol known to react with cysteines of glutathione transferases (GSTs).

In addition to their role in detoxification, bacterial GSTs are also involved in a variety of distinct metabolic processes such as the biotransformation of dichloromethane, the degradation of lignin and atrazine, and the reductive dechlorination of pentachlorophenol.

The hydroxysteroid sulphotransferase inhibitor, dehydroepiandrosterone sulphate, strongly retarded the covalent binding of DHBA to DNA as well as the DHBA 7-sulphate formation from DHBA in the biological system, while pentachlorophenol and dichloronitrophenol showed little effect on these reactions.

In addition to hydroxylation reactions, evidence was obtained for the conjugation of HCB with glutathione catalysed by a microsomal glutathione transferase.
Hexachlorobenzene (HCB) was metabolised by phenobarbital-induced liver microsomes from male rats to pentachlorobenzene, pentachlorophenol, tetrachloro-1,2-benzenediol and tetrachloro-1,4-benzenediol (1:88:2:9).

Tetrachloro-1,4-hydroquinone (TClHQ) is an intermediate in the degradation of pentachlorophenol by the lignin-degrading basidiomycete Phanerochaete chrysosporium.
This membrane-bound glutathione transferase was specific for GSH as a cosubstrate.

The greatest total gradient between bile and water CP was 5.2 X 10 (4) for pentachlorophenol.
In contrast to PSMO, activities of conjugating enzymes (p-nitrophenol UDP-glucuronosyl and glutathione transferases) were decreased in the liver.

However, the binding of HNOH-MeIQx to DNA in hepatocytes was independent of sulfotransferase since inhibitors of this enzyme, 2,6-dichloro-4-nitrophenol (DCNP) and pentachlorophenol (PCP), did not diminish DNA binding.
The nitro derivative of MeIQx, a direct-acting bacterial mutagen, was readily detoxified by glutathione transferase, forming a conjugate where the thiol group of glutathione displaced the nitro moiety.
