  • Title: Localization, isolation and characterization of Mn-superoxide dismutase in bovine adrenocortical cells.
    Author: Yamakura F, Ono Y, Ohmori D, Suzuki K.
    Journal: Comp Biochem Physiol B; 1984; 79(1):33-9. PubMed ID: 6499410.
    Abstract:
    Cyanide-insensitive superoxide dismutase activity was present in both cytosol (26%) and mitochondrial (64%) fractions of bovine adrenal cells. The cyanide-insensitive superoxide dismutase was isolated from the mitochondrial fraction. It contained 2.2 g atoms of manganese per mol of enzyme. The enzyme had a molecular weight of 82,000 and a subunit molecular weight of 22,000. The isoelectric point, amino acid composition, and spectra of visible and ultraviolet regions were similar to those of the Mn-superoxide dismutase from the other mitochondria.
