ABSTRACT:
Myoglobin is shown to have Manganese (Mn.sup.2') binding and peroxidase capacity. Mn binding and peroxidase activity is enhanced by modification of the amino acid sequence of myoglobin to provide a Mn binding site on the surface of the protein near the heme group. Peroxidase activity of myoglobin not specific to Mn is enhanced by substituting amino acids at residues 39, 45, 46, 97 and 107 of myolglobin.
