Catalase-peroxidase (EC 1.11.1.21, katG (gene)) is an enzyme with systematic name donor:hydrogen-peroxide oxidoreductase.
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 ...
In molecular biology, the DyP-type peroxidase family is a family of haem peroxidase enzymes. Haem peroxidases were originally divided into two superfamilies, namely, the animal peroxidases and the plant peroxidases (which are subdivided into class I, II and III), which include fungal (class II) and bacterial peroxidases. The DyP (for dye de ...
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 ...
Class I, the intracellular peroxidases, includes: cytochrome c peroxidase (CCP), a soluble protein found in the mitochondrial electron transport chain, where it probably protects against toxic peroxides; ascorbate peroxidase (AP), the main enzyme responsible for hydrogen peroxide removal in chloroplasts and cytosol of higher plants; [4] and ...
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 NADPH peroxidase (EC 1.11.1.2) is an enzyme that catalyzes the chemical reaction NADPH + H + + H 2 O 2 ⇌ {\displaystyle \rightleftharpoons } NADP + + 2 H 2 O The 3 substrates of this enzyme are NADPH , H + , and H 2 O 2 , whereas its two products are NADP + and H 2 O .
This is different from most peroxidases, which have the second oxidising equivalent on the porphyrin instead. Compound I of CCP is fairly long-lived, decaying to CCP-compound II with a half-life at room temperature of 40 minutes to a couple hours. CCP has high sequence identity to the closely related ascorbate peroxidase enzyme.
