The peroxidase catalyzed oxidation of indole-3-acetate is inhibited by naturally occurring coumarins such as scopoletin. This inhibition is due to the preferential reactivity of the coumarins with the ...

IT was previously shown 1,2 that methæmoglobin forms with hydrogen peroxide and ethyl hydroperoxide reversible compounds analogous to those which it forms with cyanide, sulphide, azide and fluoride.

All aerobic biological systems, including N2-fixing root nodules, are subject to O2 toxicity that results from the formation of reactive intermediates such as H2O2 and free radicals of O2. H2O2 may be ...

Figure 1. Comparison of the catalytic activities of various nanozymes and horseradish peroxidase (HRP) toward TMB and H2O2. (Image: KAIST) Enzymes are the main catalysts in our body and are widely ...
