  • Title: [Glutathione:dehydroascorbate oxidoreductase activity in rabbit eye tissues].
    Author: Bogdanova IA, Gerasimov AM, Komarov OS.
    Journal: Vopr Med Khim; 1987; 33(3):104-7. PubMed ID: 3630002.
    Abstract:
    Glutathione: dehydroascorbate oxidoreductase was detected in rabbit eye tissues, activity of which was decreased as compared with that of glutathione reductase. The ratio between glutathione reductase activity and the total activity of the enzymes catalyzing glutathione oxidation (glutathione: dehydroascorbate oxidoreductase and glutathione: H2O2 peroxidase) was above one unit in cornea, ciliary body, sclera vascular tunic and iris of the eye; it was lower than one unit in vitreous body, lens, optic nerve and aqueous humor. Glutathione: dehydroascorbate oxidoreductase is one of the key component in the eye antioxidative system; it regulates the ratio of oxidized and reduced forms of ascorbic acid and glutathione.
