Induction of anionic glutathione transferases in rat liver by propylthiouracil
Abstract:
The treatment of rats with propylthiouracil (PTU) resulted in an induction of not only cationic but also anionic glutathione (GSH) transferases. DE-52 column chromatography of the anionic GSH transferases divided into five main peaks (I-V). Peaks I-IV had a high activity toward 1-chloro-2,4-dinitrobenzene (CDNB). Peak V, which is a new form of the enzyme, showed high activity to ethacrynic acid. PTU induced peaks I and V, whereas phenobarbital increased the activity of only peak I.
