Horseradish peroxidase is also commonly used in techniques such as ELISA and Immunohistochemistry due to its monomeric nature and the ease with which it produces coloured products. Peroxidase, a heme-containing oxidoreductase, is a commercially important enzyme which catalyses the reductive cleavage of hydrogen peroxide by an electron donor.
Horseradish peroxidase has an accessible active site, and many compounds can reach the site of the reaction. On the other hand, for an enzyme such as cytochrome c peroxidase , the compounds that donate electrons are very specific, due to a very narrow active site.
TMB can act as a hydrogen donor for the reduction of hydrogen peroxide to water by peroxidase enzymes such as horseradish peroxidase.. Shows the oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) to 3,3',5,5'-tetramethylbenzidine diimine

Animal heme-dependent peroxidases is a family of peroxidases.Peroxidases are found in bacteria, fungi, plants and animals. On the basis of sequence similarity, a number of animal heme peroxidases can be categorized as members of a superfamily: myeloperoxidase (MPO); eosinophil peroxidase (EPO); lactoperoxidase (LPO); thyroid peroxidase (TPO); prostaglandin H synthase (PGHS); and peroxidasin.
Cooking the pasta al dente is key to ensuring it has just the right bite. Related: The #1 Chef-Approved Trick to Making a Better Pasta Dish. And while pasta is always delicious, roasting the ...
Horseradish peroxidase is also capable of oxidizing these substrates, but its heme is not covalently bound and becomes damaged during turnover. [4] A specific vanadium bromoperoxidase in marine organisms (fungi, bacteria, microalgae, perhaps other eukaryotes) uses vanadate and hydrogen peroxide to brominate electrophilic organics. [5]
The book really reflects the back-and-forth, in-the-moment kitchen conversations between a novice home cook and a pro—and Hall asks lots of questions that many home cooks have.
