Iodide modulation of the EDTA-induced iodine reductase activity of horseradish peroxidase by interaction at or near the EDTA-binding site.

Horseradish peroxidase (HRP) catalyses the reduction of iodinium ion (I+) to iodide by H2O2 in the presence of EDTA. I+ reduction occurs optimally at pH 6 whereas the enzyme catalyses iodide oxidation optimally at pH 3.5. Thus the two activities reside on the same enzyme with two characteristic pH o...
