| Uses | Peroxidases (EC 1.11.1.x) are a diverse group of oxidoreductases using peroxide
as an electron acceptor. Their substrate spectrum ranges from hydrogen peroxide
decomposed by catalase (hydrogen-peroxide:hydrogen-peroxide oxidoreductase,
EC 1.11.1.6), phenolic compounds degraded by Mn-dependent and lignin peroxidases
(Mn(II):hydrogen-peroxide oxidoreductase, EC 1.11.1.13 and 1,2-bis
(3,4-dimethoxyphenyl)propane-1,3-diol:hydrogen-peroxide oxidoreductase, EC
1.11.1.14), and recalcitrant dyes by DyP-type peroxidases (reactive-blue-
5:hydrogen-peroxide oxidoreductase, EC 1.11.1.19).
Direct supplementation of peroxidases to food was applied for the degradation
of carotenoids used for coloring of cheese. The whey resulting from colored
cheese production has an orange-yellowish tint, which interferes with further usage
of the whey. Recently, a fungal peroxidase of the DyP-type was commercialized
for bleaching of this kind of whey fluid under the name MaxiBright (DSM). To
generate the hydrogen peroxide required by the peroxidase as a cofactor in situ, a
glucose oxidase and a b-galactosidase were employed as auxiliary enzymes. |
| Uses | lactoperoxidase is a glycoprotein with anti-microbial activity, it is used as a stabilizing ingredient to help improve formulation stability and product shelf-life. It is naturally occurring in milk. |
| Uses | Peroxidase, horseradish is used in the oxidation of luminol to 3-aminophthalate. It is often used in conjugates to determine the presence of a molecular target, especially in the detection of specific protein in a western blot after conjugation with antibody. Further, it is highly reactive toward human tumor cells. |
| Definition | ChEBI: N-(2-aminophenyl)-4-[[[4-(3-pyridinyl)-2-pyrimidinyl]amino]methyl]benzamide is a member of benzamides. |
| General Description | Protein G is a bacterial cell wall protein, which has high affinity for immunoglobulin G (IgG). It is isolated from group G streptococcal strains. Peroxidase from Streptococcus sp. is used to maintain the H2O2 homeostasis in cells. It aids the regulation of ABC Mn2+-permease complex (psaBCA) genes. |
| Flammability and Explosibility | Notclassified |
| Biochem/physiol Actions | The transformation of industrial dyes by manganese peroxidases from Bjerkandera adusta is a manganese-independent reaction . |
