On the two electrophoretic forms of the Human superoxide dismutase A in the homozygote SOD A1

  • N. Crosti


Human superoxide dismutase A of the common phenotype SOD A1 is present in two electrophoretic forms in erythrocytes. These forms are charge isomers, easily permuting one into the other. Oxidation and reduction of the copper, partial or complete saturation of the dimers with copper, and presence of thiol groups on the enzyme do not seem to be involved.
