- Abstract
The complete amino acid sequence of manganese superoxide dismutase from human liver was determined. The sequence was deduced following characterization of the peptides obtained from tryptic, chymotryptic, and Staphylococcus aureus digests of the apoprotein. Chemical cleavage with dimethyl sulfoxide-hydrobromic acid was also carried out. The amino acid sequence listed below is made up of 196 amino acids and the two subunit polypeptides in the native enzyme appear to be identical. No homology was observed with copper/zinc containing class of superoxide dismutase.
