Oxidase

Oxidase (from Latin oxidum - acid and suffix -aza) is an enzyme of the class of oxidoreductases that catalyzes redox reactions involving molecular oxygen as an electron acceptor.

Oxidases accelerate the oxidation reactions of various substrates (for example, amino acids, aldehydes, polyamines) with oxygen to form peroxides, superoxide anions and other reactive oxygen species. They play an important role in the detoxification of xenobiotics, the biosynthesis of hormones, neurotransmitters and other biologically active substances. Disruption of oxidases often leads to the development of pathological conditions.

Oxidases are widespread in nature, found in bacteria, fungi, plants and animals. They are localized mainly in the cytoplasm, mitochondria, peroxisomes and cell membranes. Depending on the type of substrate, different types of oxidases are distinguished: monoamine oxidases, D-amine oxidases, L-amine oxidases, polyamine oxidases, aldehyde oxidases, xanthine oxidases and others.

Oxidase is an enzyme involved in the oxidation process and is a key element in many metabolic processes in living organisms. Oxygenase is a type of oxidase that can catalyze the oxidation of molecular oxygen to produce water. Some of the main functions performed by the oxidase include regulating the Krebs cycle, producing mitochondrial respiration, and controlling vitamin and protein metabolism. In this article we will look in more detail at what oxidase is and what its main functions are in the human body.

Definition and Chemical Structure Oxygenase is an enzyme that is found in the cytoplasm of most eukaryotic cells, such as plant, animal and fungal cells. The enzyme consists of two components: the active enzyme and a soluble coenzyme called flavin (vitamin B2). Most oxidases have a typical structure of three domains: inhibitor, catalytic and electron transport center. An inhibitor is a group of amino acid residues that bind the active site and reduce the rate of the oxidation reaction. The catalyst is a binary system in which the flavin is held in contact
