Mechanism of peroxidase-catalyzed oxidation. Substrate-substrate activation in horseradish peroxidase-catalyzed reactions

The structure and functions of peroxidases are characterized. Attention is focused on the mechanisms of action of horseradish peroxidase in reactions with different substrates and on correlations between structure and functions of various heme-containing proteins. The phenomenon of substrate-substrate activation typical of peroxidase-catalyzed reactions is discussed.
