Three forms of superoxide dismutase are present in humans, in all other mammals, and most chordates. SOD1 is located in the cytoplasm, SOD2 in the mitochondria, and SOD3 is extracellular. The first is a dimer (consists of two units), whereas the others are tetramers (four subunits). SOD1 and SOD3 contain copper and zinc, whereas SOD2, the mitochondrial enzyme, has manganese in its reactive centre. The genes are located on chromosomes 21, 6, and 4, respectively (21q22.1, 6q25.3 and 4p15.3-p15.1).

Famous quotes containing the word human:
“Poor America, of what avail is all her wealth, if the individuals comprising the nation are wretchedly poor? If they live in squalor, in filth, in crime, with hope and joy gone, a homeless, soilless army of human prey.”
—Emma Goldman (18691940)
“We all want to help one another. Human beings are like that.”
—Charlie Chaplin (18891977)
“Whenever a human being, through the commission of a crime, has become exiled from good, he needs to be reintegrated with it through suffering. The suffering should be inflicted with the aim of bringing the soul to recognize freely some day that its infliction was just.”
—Simone Weil (19091943)
