Compound as reactive (2)

H₂O + N¹-acetylspermidine + oxygen → hydrogen peroxide + 3-acetamidopropanal + putrescine

H2O + oxygen + N1-acetylspermidine → hydrogen peroxide + 3-aminopropanal + N-acetylputrescine

Compound as product (3)

H₂O + N¹,N¹²-diacetylspermine + oxygen → hydrogen peroxide + 3-acetamidopropanal + N¹-acetylspermidine

H₂O + N¹-acetylspermine + oxygen → hydrogen peroxide + 3-aminopropanal + N¹-acetylspermidine

acetyl-CoA + spermidine → N¹-acetylspermidine + H⁺ + coenzyme A

Reversible reaction (1)

spermidine + acetyl-CoA ↔ coenzyme A + N¹-acetylspermidine + H⁺
