A previously uncharacterized glutathione S-transferase isoenzyme which is absent from normal adult rat livers has been isolated from fetal rat livers. The enzyme was purified using a combination of affinity chromatography, CM-cellulose column chromatography and chromatofocusing. It is composed of two non-identical subunits, namely, subunit Yc (Mr 28,000) and a subunit (Mr 25,500) recently reported by us to be uniquely present in fetal rat livers and which we now refer to as subunit 'Yfetus'. The enzyme which we term glutathione S-transferase YcYfetus has an isoelectric point of approx. 8.65 and has glutathione S-transferase activity towards a number of substrates. The most significant property of the fetal isozyme is its high glutathione peroxidase activity towards the model substrate cumene hydroperoxide. We suggest that this isozyme serves a specific function in protecting fetuses against the possible teratogenic effects of organic peroxides.
