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 -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00198};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_00198}.
CC -!- SIMILARITY: Belongs to the spermidine/spermine synthase family.
CC {ECO:0000256|ARBA:ARBA00007867, 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: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
