Colorimetric estimation of diamine oxidase activity
Analytical Biochemistry, 1975Abstract A simple colorimetric method for estimation of DAO activity with 4-nitrobenzylamine as a substrate (9,10) was developed. Sensitivity of this method, based on conversion of the aldehyde formed in course of the enzymatic reaction into its 4-nitrophenylhydrazone with subsequent measuring of optical density at 590 nm in strongly alkaline medium,

Purification of human intestinal diamine oxidase
Inflammation Research, 1996Diamine oxidase (DAO; EC 1.4.3.6) catalyzes the oxidative deamination of histamine and other biogenie amines [1]. In mammals, degradation by DAO is the major pathway ofhistamine inactivation in many organs, especially in the intestine where the highest activities of DAO have been reported [2].

Inhibition of Diamine Oxidase Activity by Metronidazole
Biochemical and Biophysical Research Communications, 1995Metronidazole was found to be a non-competitive inhibitor of man, rabbit and rat intestinal diamine oxidases with an inhibition constant value of approximately 10(-4) M. The purified bovine serum amine oxidase was not inhibited, whereas the purified swine kidney enzyme gave similar results.

Serum Diamine Oxidase in Pregnancy and in Trophoblastic Diseases
The Journal of Clinical Endocrinology & Metabolism, 1970ABSTRACT Serum diamine oxidase levels are significantly elevated during normal pregnancy. In normal pregnancy the activity of this enzyme and the urinary excretion of gonadotropin are inversely related. As HCG starts to decline from the peak value, diamine oxidase appears in the blood and the level increases rapidly to high values while the HCG is ...
