ABSTRACT

The ambitious goal of biomimetic chemistry to mimic the structural and functional aspects of natural enzymes is at the center of interest by contemporary scientists. Peroxidases are the first group of enzymes that could efficiently be mimicked by inorganic nanomaterials. They play a very important role in many organisms by reducing cellularly generated toxic hydrogen peroxide. Peroxidases, including horseradish peroxidase, are used in analytical and clinical chemistry for the enzyme-catalyzed conversion of colorimetric substrates in signaling and imaging applications. Haloperoxidases represent a class of enzymes with the capability of catalyzing the oxidation of halides using hydrogen peroxide to form hypohalous acids. superoxide dismutases catalyzes the dismutation of superoxide radicals into elemental oxygen and hydrogen peroxide and play a major role in aerobic organisms in their defense mechanisms against oxidative stress. Molybdenum trioxide is a well-known and widely used material for selective oxidation catalysis, but its biocatalytic behavior is virtually unknown.
