A specific glutathione S-transferase isozyme occurring in hereditary hyperbilirubinuria rats.
A glutathione S-transferase isozyme which is absent in normal rat liver has been isolated from the hereditary hyperbilirubinuria rat liver cytosol. The enzyme was purified to apparent homogeneity by GSH-affinity chromatography and HPLC on CM-Sepharose CL-6B. It is a heterodimer of two non-identical subunits, i.e., subunit 2 and a previously uncharacterized subunit referred to here as subunit Yx. Immunoblot analysis indicated that GST 2-Yx belongs to the alpha class. GST 2-Yx is characterized by its 4-fold higher activity towards 4-hydroxy-non-2-enal, compared to that of GST 2-2.
