== Function ==
 +
[https://www.uniprot.org/uniprot/SPEE_HUMAN SPEE_HUMAN] Catalyzes the production of spermidine from putrescine and decarboxylated S-adenosylmethionine (dcSAM). Has a strong preference for putrescine as substrate, and has very low activity towards 1,3-diaminopropane. Has extremely low activity towards spermidine.

== Publication Abstract from PubMed ==
 +
Aminopropyltransferases transfer aminopropyl groups from decarboxylated S-adenosylmethionine to amine acceptors, forming polyamines. Structural and biochemical studies have been carried out with the human spermidine synthase, which is highly specific for putrescine as the amine acceptor, and the Thermotoga maritima spermidine synthase, which prefers putrescine but is more tolerant of other substrates. Comparison of the structures of the human spermidine synthase with both substrates and products with the known structure of T. maritima spermidine synthase complexed to a multisubstrate analogue inhibitor and analysis of the properties of site-directed mutants provide a general mechanistic hypothesis for the aminopropyl transfer reaction. The studies also provide a structural basis for the specificity of the spermidine synthase subclass of the aminopropyltransferase family.
