Metabolism of acetylpolyamines by monoamine oxidase, diamine oxidase and polyamine oxidase
Biochimica et Biophysica Acta (BBA) - 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 ...

Highly efficient purification of porcine diamine oxidase
Journal of Chromatography B: Biomedical Sciences and Applications, 2000Diamine oxidase (DAO) is a member of the class of copper-containing amine oxidases and catalyzes the oxidative deamination of histamine and other biogenic amines. The enzyme from porcine kidney was purified by consecutive chromatography on concanavalin A Sepharose, heparin Sepharose and Mono Q.

Studies on Diamine Oxidase Activity During Pregnancy
Acta Obstetricia et Gynecologica Scandinavica, 1971The diamine oxidase activities (diamine: oxygen oxidoreductase (deaminating), (EC 1.4.3.6)) of amniotic fluid, maternal venous plasma and fetal plasma were measured in 19 pregnant women at term. No statistically significant difference was found between the enzyme activity of the amniotic fluid and the maternal plasma.

Inhibition of diamine oxidase by antimalarial drugs
Agents and Actions, 1980The antimalarial drugs amodiaquine, quinacrine and chloroquine inhibit the catabolism of putrescine by the rat. Amodiaquine, the most potent of the three, does so in a dose-dependent fashion. This is attributed to the action in vivo of the drugs on diamine oxidase, an enzyme that is inhibited by them in vitro.

[239] Diamine oxidase (pig kidney)
1971Publisher Summary This chapter discusses the methods of preparation of Diamine Oxidase (Pig Kidney). Although spectrophotometric methods have been described, the chapter describes the most commonly used procedure of assay, which is a manometric one. A qualitative assay is also described (oxyhemoglobin test).

Factors affecting plasma postheparin diamine oxidase activity
Digestive Diseases and Sciences, 1991Plasma postheparin diamine oxidase (DAO) activity has been evaluated for assessing disease activity in Crohn's disease (CD) and other intestinal disorders. Since the mechanism of the reduced plasma DAO activity is poorly understood, our aim was to determine the effect of extent and location of disease and prior resection and therapy on plasma DAO ...

Intestinal diamine oxidase levels reflect ischemic injury
Journal of Surgical Research, 1991Mucosal diamine oxidase (DAO) decreases during intestinal ischemia and may be a useful marker of intestinal ischemic injury. Tissue DAO activity and histologic changes were studied in intestinal segments taken from the midpoint of the small intestine before and 2, 4, and 24 hr after manipulation of the intestinal blood supply in 24 mongrel dogs ...

Intestinal diamine oxidase of some teleostean fishes
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. The intestinal diamine oxidase of some teleostean fishes was assayed using 14C-putrescine as substrate. 2. 2. Diamine oxidase could easily be detected in all species investigated. The most active preparation (Coryphaenoides rupestris) was about thirty times as active as the least active one (Gadus poutassou). 3. 3.

[238] Diamine oxidase (pea seedling)
1971Publisher Summary This chapter discusses the methods of preparation of Diamine Oxidase (Pea Seedling). The method is based on measuring the uptake of oxygen in the presence of catalase, with putrescine (1,4-diaminobutane) as the substrate. Cadaverine (1,5-diaminopentane) has been used in the assay of other amine oxidases, but cannot be used with ...
