Diaminoxidase (DAO, Histaminase) ist ein kupferhaltiges Enzym, das Histamin, Putreszin und andere biogene Amine abbauen kann. The main enzyme for metabolizing ingested histamine is diamine oxidase (DAO). The following video shows how this happens (here are the slides from the video). The molecular mass of the enzyme is found to be 170 kDa. Each subunit contains one molecule of pyridoxal phosphate and one atom of copper. + This oxidoreductase article is a stub. Many other diamine oxidase inhibitors also inhibit sperm motility. Diamine oxidase (DAO), also known "amine oxidase, copper-containing, 1" (AOC1), formerly called histaminase, is an enzyme (EC 1.4.3.22) involved in the metabolism, oxidation, and inactivation of histamine and other polyamines such as putrescine or spermidine in animals. As with most enzymes in your body, there is no way that you can increase the amount your body manufactures. {\displaystyle \mathrm {R{-}CH_{2}{-}NH_{2}+H_{2}O+O_{2}\longrightarrow R{-}CHO+NH_{3}+H_{2}O_{2}} }, + H2O + O2 Pipette (in milliliters) the following reagents into suitable cuvettes: Es wird von Zellen der Darmschleimhaut, den Enterozyten, produziert. Our enzyme Diamino Oxidase (DAO) of animal, plant and biotechnological origin ensures maximum activity in the process of degradation of histamine from food due to its greater structural and functional similarity with human DAO (its DAO activity is 22,000 HDU , similar to the activity of 100% pure human DAO). Diamine oxidase enzyme breaks histamine down and keeps blood histamine in the normal range. Der direkte Gegenspieler des Histamins ist das sekretorische Enzym Diaminooxidase (DAO).Ein zweiter Weg der Regulation läuft über das Enzym Histamin-N-Methyltransferase (HNMT). The highest levels of DAO expression are observed in the digestive tract and the placenta. Diamine oxidase from porcine kidney has also been used in a study to investigate N-linked oligosaccharide structures in diamine oxidase. hDAO has been cloned and expressed in insect cells and the structure of the native enzyme determined by X-ray crystallography to a resolution of 1.8 A.

Mammalian intestinal mucosa contains an endogenous DAO, … H Eine zu geringe Diaminoxidase-Aktivität führt zu einem Mißverhältnis zwischen Histaminaufnahme mit der Nahrung … Das Enzym wird von allen Chordatieren gebildet. [4], Ein Präparat mit der aus Schweinenierenextrakt gewonnenen Zutat Diaminoxidase wird in Kapselform angeboten, mit der Zweckbestimmung "zur diätetischen Behandlung von histaminbedingten Lebensmittelunverträglichkeiten" (Histamin-Intoleranz), allerdings konnte in wissenschaftlichen Tests keinerlei DAO-Aktivität darin festgestellt werden. The most active class of these sperm motility inhibitors is the group of isothiuronium compounds, some of which are much more potent than many other metabolic inhibitors tested. Diamine oxidase is the amiloride-binding protein and is inhibited by amiloride analogues. Diamine Oxidase delivers a patented formulation of Diamine Oxidase that releases in the small intestine, where it acts directly on dietary histamine to support digestive health and total-body comfort. Beim Menschen wird es im Darm, den Nieren und in der Plazenta produziert. 2 2 [6] Vermutet wird, dass die DAO so Mutter und Kind vor übermäßigem Histamin schützt, da dieses zu Schwangerschaftskomplikationen führen kann.
