Hemoproteins
complex proteins containing the pigmented prosthetic group—hemes. Hemoproteins are classified as chromoproteins. In addition to the respiratory pigments—hemoglobin and myoglobin—hemoproteins include widely distributed respiratory enzymes—cytochromes— and oxidative enzymes of tissues—peroxidase, which catalyzes the oxidation of organic substances by hydrogen peroxide, catalase, and leghemoglobin (legoglobin), a pigment found in the root nodules of leguminous plants.

The antioxidant properties of Ergothioneine appear to be related to at least four molecular activities: the ability to scavenge free radicals; to chelate, or combine with, various divalent metallic cations (positively charged ions); to activate antioxidant enzymes such as glutathione peroxidase (Se-GPx) and MnSOD and to inhibit superoxide-generating enzymes such as NADPH-Cytochrome c reductase; and to affect the oxidation of various hemoproteins such as hemoglobin and myoglobin.
