Abstract
The nitrogen and the iron contents of the "active product" are 15.3% and 0.21% respectively. The S[image] and molecular weight of the "active product" are 2.6 s and 27,500 respectively. The "active product" contains 248 amino acid residues/molecular assuming a molecular weight of 27,500. The properties of the "active product" and catalase are compared and the relationship between their structures and enzyme activity is discussed.
