Peroxidase

Использование

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.

Биологические функции

Peroxidases are widely distributed in plants, animals, and microorganisms, and they protect cells against the effects of oxidative stress and cell damage due to H2O2. Peroxidases (EC number 1.11.1.x) represent a large family of oxidoreductases known to catalyze the oxidation of various inorganic and organic substrates using H2O2. They have a common catalytic mechanism for the degradation of H2O2, a two-electron oxidation-reduction with three distinct steps. They are involved in biological processes such as the breakdown of toxins, heavy metal detoxification and hormone regulation. Additionally, they are used as catalysts in various industries, in clinical biochemistry, enzyme immunoassays, the removal of peroxides from industrial wastes and the synthesis of various aromatic chemicals[1].

Общее описание

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.
