SOD1 is one of three oxidoreductase enzymes that is responsible for binding copper and zinc ions to highly reactive oxygen free radicals and transforming them into oxygen and hydrogen peroxide <ref name="McCord">McCord JM, Fridovich I.

The SOD 1 protein | The SOD 1 protein is a homodimer with an amino acid sequence length of 154. SOD 1 has an 8-stranded "Greek key" beta-barrel shape with the active site located between the barrels. ligands of the copper and zinc are six histidine and one aspartate side-chains; one histidine is shared between the two metals<ref name="Tainer">Tainer JA, Getzoff ED, Richardson JS, Richardson DC.
