A membrane-bound glutathione S-transferase and a soluble glutathione conjugate reductase constitute the reductive dehalogenase system of P. chrysosporium.
This enzyme system reductively removes chlorine substituents from tetrachlorohydroquinone, a metabolite of pentachlorophenol.

Tetrachlorohydroquinone dehalogenase catalyzes the reductive dehalogenation of tetrachlorohydroquinone and trichlorohydroquinone during the biodegradation of the xenobiotic compound pentachlorophenol by Sphingobium chlorophenolicum.
Tetrachlorohydroquinone dehalogenase is a member of the glutathione S-transferase superfamily.

The metabolism and covalent binding of OTA to DNA were investigated in vitro with cytochromes P450, glutathione S-transferases, prostaglandin H-synthase, and horseradish peroxidase.
There was no evidence of DNA adduct formation when [(3) H] OTA was incubated with these enzyme systems in the presence of calf thymus DNA (<20 adducts/10 (9) DNA bases); however, these enzymes catalyzed DNA adduct formation with the genotoxins aflatoxin B (1), 2-amino-3-methylimidazo [4,5-f] quinoline, benzo [a] pyrene, and pentachlorophenol.

Tetrachlorohydroquinone (TCHQ) dehalogenase catalyzes the conversion of TCHQ to 2,6-dichlorohydroquinone during degradation of pentachlorophenol by Sphingobium chlorophenolicum.
TCHQ dehalogenase is a member of the glutathione S-transferase superfamily.
