Quantification of human diamine oxidase.
Clinical Biochemistry, 2017Diamine oxidase (DAO) is essential for extracellular degradation of histamine. For decades activity assays with inherent limitations were used to quantify the relative amounts of DAO. No reference DAO standard is available. Absolute DAO amounts cannot be determined. Controversy exists, whether DAO is circulating or not in non-pregnant individuals.

Metabolism of acetylpolyamines by monoamine oxidase, diamine oxidase and polyamine oxidase
Biochimica Et Biophysica Acta - General Subjects, 1981N1-Monoacetylspermine, N1,N12-diacetylspermine and N1-monoacetylspermidine were found to be good substrates for rat liver polyamine oxidase, but not for rat liver mitochondrial monoamine oxidase. N8-Monoacetylspermidine, monoacetylcadaverine, monoacetylputrescine and monoacetyl-1,3-diaminopropane were oxidized by the monoamine oxidase when the ...

Food Chemistry, 2022
Aiming at enhancing the biosensing detection of histamine in foods at high temperature, we developed a thermoregulatory biosensor based on diamine oxidase-immobilized phase-change microcapsules consisting of an n-docosane core, a TiO2 shell, and an ...

Agents and Actions, 1983
In adult hens diamine oxidase (histaminase) activity was found in gastrointestinal tract (with the highest value in ileum), liver and spleen. Intestinal diamine oxidase is predominantly a particle-bound enzyme. In the intestine oxidation of putrescine leads to delta 1-pyrroline formation, in liver both delta 1-pyrroline and gamma-aminobutyric acid are ...

Inhibition of diamine oxidases and polyamine oxidases by diamine-based compounds
Journal of Neural Transmission, 2007This review reports on inhibitors of copper-containing amine oxidases and flavoprotein polyamine oxidases, which are structurally based on diamines. In the introduction, basic characteristics and classification of amine oxidases are described together with the significance of their synthetic inhibitors.

Serum Diamine Oxidase in the Neonate
Biology of the Neonate, 2009Serum diamine oxidase (DAO) activities were measured in 9 pregnant women and in 33 neonates during the 1st week of life. The radiometric method was used. Very high values were found in the mothers (mean ± SE: 720 ± 143 pmol ml-1 h-1) Neonates showed significantly elevated values (mean ± SE: 178 ± 54 pmol ml-1 h-1) on the 1st postnatal day when compared

Differentiation of monoamine oxidase and diamine oxidase
Biochemical Pharmacology, 1962Abstract In kidney of cats pretreated with inhibitors of monoamine oxidase and diamine oxidase the activity of these enzymes was measured simultaneously, using typical cell fractions and substrates. After iproniazid pretreatment inhibition of diamine oxidase occurred somewhat earlier and was of shorter duration than inhibition of monoamine oxidase ...

Inhibition of diamine oxidase by bulbocapnine
Biochemical Pharmacology, 1962Abstract Using a modification of the spectrophotofluorometric method of Shore, Burkhalter and Cohn, an inhibition of diamine oxidase by bulbocapnine, using histamine as a substrate, has been demonstrated. The mechanism of the inhibition is competitive, as indicated by Lineweaver-Burke and Hunter-Downs plots.

Subcellular distribution of diamine oxidase
Comparative and General Pharmacology, 19701. 1. Subcellular distribution of diamine oxidase (DAO) was studied in various mammalian tissues using differential centrifugation. 2. 2. Highest DAO activity was found in the 600 g pellets (nuclear fraction) of the following tissues: kidney cortex (cat and dog), cat intestine, rabbit placenta, and rat uterus with deciduomata. 3. 3.
