Enzyme Information
| 1.5.3.15 | N(8)-acetylspermidine oxidase (propane-1,3-diamine-forming). based on mapping to UniProt O64411 N(8)-acetylspermidine + O(2) + H(2)O = propane-1,3-diamine + 4-acetamidobutanal + H(2)O(2). -!- Also active with N(1)-acetylspermine, weak activity with N(1),N(12)- diacetylspermine. -!- No activity with diaminopropane, putrescine, cadaverine, diaminohexane, norspermidine, spermine and spermidine. -!- Absence of monoamine oxidase (EC 1.4.3.4) activity. -!- Differs in specificity from EC 1.5.3.13, EC 1.5.3.14, EC 1.5.3.16 and EC 1.5.3.17. -!- Formerly EC 1.5.3.11, EC 1.5.3.n6, EC 1.5.3.n7, EC 1.5.3.n8 and EC 1.5.3.n9. | 
| 1.5.3.14 | Polyamine oxidase (propane-1,3-diamine-forming). based on mapping to UniProt O64411 Spermidine + O(2) + H(2)O = propane-1,3-diamine + 4-aminobutanal + H(2)O(2). -!- As the products of the reaction cannot be converted directly to other polyamines, this class of polyamine oxidases is considered to be involved in the terminal catabolism of polyamines. -!- Catalyzes less efficiently the oxidation of N(1)-acetylspermine and spermine. -!- Differs in specificity from EC 1.5.3.13, EC 1.5.3.15, EC 1.5.3.16 and EC 1.5.3.17. -!- Formerly EC 1.5.3.11, EC 1.5.3.n6, EC 1.5.3.n7, EC 1.5.3.n8 and EC 1.5.3.n9. |
