The Purification and Properties of Superoxide Dismutase from Neurospora crassa

摘要: Abstract Soluble extracts of Neurospora crassa contain a single, electrophoretically distinct, superoxide dismutase. This enzyme has been isolated and found to be blue-green, copper- zinc-containing enzyme, similar that already described from bovine tissues garden peas. The molecular weight was approximately 31,000, the appeared composed 2 subunits equal size joined only by noncovalent interractions. contains two Cu++ Zn++ per molecule. ultraviolet absorption spectrum indicates lack tryptophan. Amino acid analyses are reported as spectral catalytic properties.
