In enzymology, a polyamine oxidase () is an enzyme that catalyzes the chemical reaction :N1-acetylspermine + O2 + H2O N1-acetylspermidine + 3-aminopropanal + H2O2 The 3 substrates of this enzyme are N1-acetylspermine, O2, and H2O, whereas its 3 products are N1-acetylspermidine, 3-aminopropanal, and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is N1-acetylspermidine:oxygen oxidoreductase (deaminating). This enzyme is also called 1-N-acetylspermidine:oxygen oxidoreductase (deaminating). It has 2 cofactors: FAD, and Iron. A similar enzyme in plants catalyzes non-acetylated polyamines. ==Structural studies== As of late 2007, 9 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , , and . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「polyamine oxidase」の詳細全文を読む スポンサード リンク
