Spermine Oxidase: an Amine Oxidase with Specificity for Spermine and Spermidine
Sheep serum and bovine serum contain an enzyme which brings about a rapid oxidative deamination of certain biological amines. This enzyme differs from previously described amine oxidases in several regards and especially in its substrate specificity. Studies thus far indicate that only spermine and the closely related compound spermidine serve as substrates for the enzyme in sheep serum. For th...
متن کاملOxidation 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 کاملInhibition of monoamine oxidase by stilbenes from Rheum palmatum
Seven stilbenes and one catechin were bioactivity-guidedly isolated from the rhizomes of Rheum palmatem. Their structures were identified as piceatannol(1), resveratrol(2), piceid(3), rhapontigenin(4), piceatannol-3'-O-β-D-glucopyranoside(5), rhaponticin(6), catechin(7) and desoxyrhapontigenin(8). Anti-monoamine oxidase (MAO) activities of compounds 1–8 were tested. Compounds 1 and 8 showed sig...

متن کاملInhibition of bovine plasma semicarbazide-sensitive amine oxidase by caffeine.
Semicarbazide-sensitive amine oxidase (SSAO) is a copper-containing enzyme that catalyzes the oxidative deamination of endogenous and exogenous primary amines. SSAO exists in mammals both as a plasma-soluble and as a membrane-bound form, and its active site is able to come into contact with numerous xenobiotic, amine-containing compounds. The kinetic studies performed in this work showed that c...
