Diamine oxidase (DAO) is an enzyme located almost exclusively in the villus tip enterocytes of mammals. Its plasma activity, normally very low, is enhanced by intravenous heparin that releases the enzyme from the enterocytes into the blood. Postheparin plasma DAO (PHD) values have been shown to...
Diamine oxidase (DAO; EC 1.4.3.6), which catabolizes a variety of substrates including histamine and diamines, is the degradative enzyme of the catabolic pathway of polyamines found in high activity in the mature upper villus cells of the rat intestinal mucosa [Luk, G.D., Bayless, T.M.,...
Inhibition of diamine oxidase promotes uptake of putrescine from rat small intestine In blood from the portal vein of anaesthetized rats the levels of histamine and putrescine were 2鈥 3-fold lower compared to arterial blood. Putrescine conc... BO Nilsson,I Kockum,E Rosengren - Inflammation resear...
1. Serum diarnine oxidase activity in control patients and during the acute and healing phase of gastroenteritis. routinely at 60 min with occasional checks of the time-activity relationship. The reaction was stopped by the addition of 10 p1 of aminoguanidine M). Fifty p1 of saturated ...
Vegetal diamine oxidase (vDAO) might be a relevant alternative owing to its histaminase activity. Mammalian intestinal mucosa contains an endogenous DAO, yet possessing lower activity compared to that of vDAO preparation. Moreover, in several pathological conditions such as inflammatory bowel disease ...
Activ- ity of benzylamine oxidase, an enzyme present in human tissues which bears similarity to the spermine oxidase of ruminant blood (22). has been found to be normal in the circulation and fibroblasts of patients with cystic fibrosis (17). Polyamines may also be metabolized through ...

Such reactions can be carried out in vivo by, for example, oxidase enzymes, oxoreductase enzymes and other oxidative enzymes. Thus, the phosphorous-containing progroups Rp can also include phosphite and phosphite ester analogs of any of the phosphate and phosphate ester progroups described above. ...
