Abstract

Two cationic (pIs 9·1 and 7·6) and one anionic (pI 4·4) forms of glutathione S-transferase have been purified to an apparent homogeneity from human cornea using glutathione-linked affinity chromatography and isoelectric focusing. The substrate specificities of the three enzyme forms are significantly different from each other. None of the three forms of human cornea glutathione S-transferase express glutathione peroxidase II activity. Immunological and structural studies reveal that human cornea enzymes have structural similarities with glutathione S-transferases of other human tissues.
