CC -!- FUNCTION: Catalyzes the irreversible transfer of a propylamine group CC from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to CC putrescine (1,4-diaminobutane) to yield spermidine. {ECO:0000256|HAMAP- CC Rule:MF_00198}. CC -!- CATALYTIC ACTIVITY: CC Reaction=putrescine + S-adenosyl 3-(methylsulfanyl)propylamine = H(+) + CC S-methyl-5'-thioadenosine + spermidine; Xref=Rhea:RHEA:12721, CC ChEBI:CHEBI:15378, ChEBI:CHEBI:17509, ChEBI:CHEBI:57443, CC ChEBI:CHEBI:57834, ChEBI:CHEBI:326268; EC=2.5.1.16; CC Evidence={ECO:0000256|HAMAP-Rule:MF_00198}; CC -!- PATHWAY: Amine and polyamine biosynthesis; spermidine biosynthesis; CC spermidine from putrescine: step 1/1. {ECO:0000256|HAMAP- CC Rule:MF_00198}. CC -!- SUBUNIT: Homodimer or homotetramer. {ECO:0000256|HAMAP-Rule:MF_00198}. CC -!- SIMILARITY: Belongs to the spermidine/spermine synthase family. CC {ECO:0000256|HAMAP-Rule:MF_00198}. CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00198}. CC -!- CAUTION: Lacks the conserved Asp active site. {ECO:0000256|HAMAP- CC Rule:MF_00198}.
