Catalysis of the reaction: S-adenosylmethioninamine + spermidine = 5'-methylthioadenosine + spermine. Catalysis of the transfer of an alkyl or aryl (but not methyl) group from one compound (donor) to another (acceptor). Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
