CC -!- FUNCTION: Involved in the biosynthesis of branched-chain polyamines,
CC which support the growth of thermophiles under high-temperature
CC conditions. Catalyzes the sequential condensation of spermidine with
CC the aminopropyl groups of decarboxylated S-adenosylmethionines to
CC produce N(4)-bis(aminopropyl)spermidine via N(4)-aminopropylspermidine.
CC {ECO:0000256|HAMAP-Rule:MF_01947}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 S-adenosyl 3-(methylsulfanyl)propylamine + spermidine = 2
CC H(+) + N(4)-bis(aminopropyl)spermidine + 2 S-methyl-5'-thioadenosine;
CC Xref=Rhea:RHEA:44132, ChEBI:CHEBI:15378, ChEBI:CHEBI:17509,
CC ChEBI:CHEBI:57443, ChEBI:CHEBI:57834, ChEBI:CHEBI:82771;
CC EC=2.5.1.128; Evidence={ECO:0000256|HAMAP-Rule:MF_01947};
CC -!- PATHWAY: Amine and polyamine biosynthesis. {ECO:0000256|HAMAP-
CC Rule:MF_01947}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01947}.
CC -!- SIMILARITY: Belongs to the branched-chain polyamine synthase family.
CC {ECO:0000256|HAMAP-Rule:MF_01947}.
