Comments
  • FUNCTION: Flavoenzyme which catalyzes the oxidation of N(1)-acetylspermine to spermidine and is thus involved in the polyamine back-conversion. Can also oxidize N(1)-acetylspermidine to putrescine. Substrate specificity: N(1)-acetylspermine = N(1)-acetylspermidine > N(1),N(12)-diacylspermine >> spermine. Does not oxidize spermidine. Plays an important role in the regulation of polyamine intracellular concentration and has the potential to act as a determinant of cellular sensitivity to the antitumor polyamine analogs.
  • CATALYTIC ACTIVITY: N1-acetylspermine + O2 + H2O = N1-acetylspermidine + 3-aminopropanal + H2O2.
  • COFACTOR: FAD.
  • PATHWAY: Amine and polyamine metabolism; spermine metabolism.
  • SUBUNIT: Monomer.
  • SUBCELLULAR LOCATION: Peroxisome (By similarity). Cytoplasm (By similarity).
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.
    Name1
    Isoform IDQ8C0L6-1
    This is the isoform sequence displayed in this entry.
    Name2
    Isoform IDQ8C0L6-2
    Features which should be applied to build the isoform sequence: VSP_011263, VSP_011264.
  • TISSUE SPECIFICITY: Widely expressed at different developmental stages. Expressed at high level in the liver and the stomach, expressed at lower level in heart, spleen, thymus, small intestine, muscle, pancreas, uterus, and breast and expressed at very low level in brain, kidney, lung, testis, skin, adrenal gland and prostate gland.
  • DEVELOPMENTAL STAGE: Expression increased during embryonic development: there is a gradual increase in the tissues on going from 8.5 to 19 day embryos. In the breast, expression is very low in virgin mouse and quite high in pregnant mouse, but decreases in lactating and involuting breasts.
  • INDUCTION: By polyamine analogs.
  • MISCELLANEOUS: Oxidizes N(1)-acetylated polyamines on the exo-side of their N(4)-amino groups. Plant PAO oxidizes spermine on the endo-side of the N(4)-nitrogen (By similarity).
  • MISCELLANEOUS: N-ethylated polyamines are also good substrates for this enzyme: they have been used for cancer clinical trials. They down-regulate polyamine biosynthetic enzymes, but dramatically up-regulate SSAT synthesis, which results in mammalian cells becoming apaptotic.
  • SIMILARITY: Belongs to the flavin monoamine oxidase family.
