- spermidine + acceptor + H2O propane-1,3-diamine + 4-aminobutanal + reduced acceptor
The 3 substrates of this enzyme are spermidine, acceptor, and H2O, whereas its 3 products are propane-1,3-diamine, 4-aminobutanal, and reduced acceptor.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donor with other acceptors. The systematic name of this enzyme class is spermidine:acceptor oxidoreductase. This enzyme is also called spermidine:(acceptor) oxidoreductase. This enzyme participates in urea cycle and metabolism of amino groups and beta-alanine metabolism. It has 2 cofactors: FAD, and Heme.
