Abstract
The subject invention provides a method for recovering a solution containing purified, enzymatically active Cu-Zn superoxide dismutase or a polypeptide analog thereof having substantially the same amino acid sequence as, and the bioloical activity of, naturally-occurring Cu-Zn superoxide dismutase from a composition which comprises cells containing Cu-Zn superoxide dismutase or a polypeptide analog thereof. The invention also provides a method of increasing the yield of recovered solutions having an increased concentration of b isoform of an enzymatically-active polypeptide analog of Cu-Zn superoxide dismutase from a composition which comprises cells containing a, b and c isoforms of the polypeptide analog.
