Oxidation of spermine by an amine oxidase from lentil seedlings.
Spermine is a substrate of lentil (Lens culinaris) seedling amine oxidase and the oxidation products are reversible inactivators of the enzyme. The spermine is oxidized at the terminal amino groups to a dialdehyde: 2 moles of hydrogen peroxide and 2 moles of ammonia per mole of spermine are formed. The pH optimum of the enzyme with spermine is 7.9 in TI-HCI buffer; the K(m) value is 4.4.10(-4) ...
متن کاملDiamine oxidase activity levels in anorexia nervosa.
OBJECTIVE Anorexia nervosa (AN) patients often experience gastrointestinal complications caused by their malnutrition. We hypothesized that intestinal integrity is disturbed in AN. Therefore, the objective of the present study was to investigate serum diamine oxidase (DAO) activity, which is considered to be a clinical indicator of the integrity of the intestinal mucosa, in AN patients. METHO...

15 صفحه اولSerum diamine oxidase activity in patients with histamine intolerance.
INTRODUCTION Intolerance to various foods, excluding bona fide coeliac disease and lactose intolerance, represents a growing cause of patient visits to allergy clinics.Histamine intolerance is a long-known, multifaceted clinical condition triggered by histamine-rich foods and alcohol and/or by drugs that liberate histamine or block diamine oxidase (DAO), the main enzyme involved in the metaboli...
متن کاملResponse of tissue diamine oxidase activity to polyamine administration.
The administration to rats of putrescine (750 mumol/kg body wt.) caused in liver, kidney and heart an increase in putrescine at 1 h and in diamine oxidase (EC 1.4.3.6) activity within 3-6 h. An increase in spermidine was observed at 9 h in liver and at 6 h in kidney, whereas in heart there was no change. The increase in diamine oxidase activity by exogenous putrescine was prevented by the admin...
