Abstract

We have purified two cationic (pI 7·2 and >10·0) forms of glutathione S-transferase from the bovine cornea through a combination of gel filtration, affinity chromatography, and isoelectric focusing. Both these glutathione S-transferases conjugate glutathione (GSH) to 1-chloro-2,4-dinitrobenzene, have an absolute requirement of GSH as the thiol donor, and do not express selenium-independent glutathione peroxidase activity. The conjugation of GSH to 1-chloro-2,4-dinitrobenzene catalyzed by the less cationic transferase is inhibited by bilirubin. Both glutathione S-transferases of the cornea have a broader spectrum of substrates that are conjugated to GSH than the glutathione S-transferases of bovine lens and retina.
