spermidine + O2 + H2O reaction is catalyzed at very low rates (at pH 7.0 and at pH 8.0). At pH 8.0, the substrate preference in decreasing order is as follows: spermine / thermospermine, N1-acetylspermine, norspermine, spermidine. At pH 7.0, the substrate preference in decreasing order is as follows: thermospermine, norspermine, spermine, N1-acetylspermine, spermidine Selaginella lepidophylla putrescine + 3-aminopropanal + H2O2
