Catalase-peroxidase (EC 1.11.1.21, katG (gene)) is an enzyme with systematic name donor:hydrogen-peroxide oxidoreductase.
The proximity extension assay (PEA) is a method for detecting and quantifying the amount of many specific proteins present in a biological sample such as serum or plasma. [1] The method is used in the research field of proteomics , specifically affinity proteomics, [ 2 ] where in one searches for differences in the abundance of many specific ...
This beetle has two sets of liquids that are stored separately in two paired glands. The larger of the pair, the storage chamber or reservoir, contains hydroquinones and hydrogen peroxide, while the smaller, the reaction chamber, contains catalases and peroxidases. To activate the noxious spray, the beetle mixes the contents of the two ...
Immunoperoxidase is a type of immunostain used in molecular biology, medical research, and clinical diagnostics.In particular, immunoperoxidase reactions refer to a sub-class of immunohistochemical or immunocytochemical procedures in which the antibodies are visualized via a peroxidase-catalyzed reaction.
There are many investigations about the use of peroxidase in many manufacturing processes like adhesives, computer chips, car parts, and linings of drums and cans. Other studies have shown that peroxidases may be used successfully to polymerize anilines and phenols in organic solvent matrices. [5] Peroxidases are sometimes used as histological ...
It is thought that catalase-peroxidase provides protection to cells under oxidative stress. [5] Class II consists of secretory fungal peroxidases: ligninases, or lignin peroxidases (LiPs), and manganese-dependent peroxidases (MnPs). These are monomeric glycoproteins involved in the degradation of lignin. In MnP, Mn 2+ serves as the reducing ...
Peroxidases have been classified into three types (class I, class II and class III): ascorbate peroxidases is a class I peroxidase enzyme. [5] APXs catalyse the H 2 O 2-dependent oxidation of ascorbate in plants, algae and certain cyanobacteria. [6] APX has high sequence identity to cytochrome c peroxidase, which
In enzymology, a manganese peroxidase (EC 1.11.1.13) is an enzyme that catalyzes the chemical reaction 2 Mn(II) + 2 H + + H 2 O 2 ⇌ {\displaystyle \rightleftharpoons } 2 Mn(III) + 2 H 2 O The 3 substrates of this enzyme are Mn(II) , H + , and H 2 O 2 , whereas its two products are Mn(III) and H 2 O .
