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 کاملPentamines as substrate for human spermine oxidase.
Substrate activities of various linear polyamines to human spermine oxidase (hSMO) were investigated. The activities were evaluated by monitoring the amount of H2O2 released from sample polyamines by hSMO. H2O2 was measured by a HPLC method that analyzed fluorescent dimers derived from the oxidation of homovanillic acid in the presence of horseradish peroxidase. Six triamines were tested and we...
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 کاملInfluence of spermine on some membrane-disturbing actions.
The influence of spermine on the potassium loss from yeast cells as a consequence of membrane-disturbing actions was investigated. Spermine interfered strongly in the action membrane-active bactericides on yeast cells; this interference resembles the action of certain metal ions. Spermine provides a protection against the positively charged parasosaniline and accomplishes a strong potentiation ...
متن کاملConsequences of Spermine Synthase or Spermidine/Spermine N- Acetyltransferase Deficiency in Polyamine Metabolism
A vast number of studies have linked polyamines to numerous cellular functions but less is known about the possible physiological functions of the individual polyamines. The specific gene targeting technique has provided a new potential way to resolve this mystery. We generated two separate embryonic stem (ES) cell lines where either spermine synthase gene (SPMSy) or spermidine/spermine N-acety...
