Phenol red hrp

The enzyme horseradish peroxidase (HRP), found in the roots of horseradish, is used extensively in biochemistry applications. It is a metalloenzyme with many isoforms, of which the most studied type is C. It catalyzes the oxidation of various organic substrates by hydrogen peroxide. WebThe phenol oxidation catalyzed by horseradish peroxidase (HRP) is slowed down by the presence of excess H2O2. This inhibition is due to accumulation of Compound III, which is a catalytically sluggish form of HRP. When HRP is polymerized through covalent bonds, Compound III becomes unstable and the p …
