>TIGR00417 speE spermidine synthase; InterPro: IPR001045 Synonym(s): Spermidine aminopropyltransferase A group of polyamine biosynthetic enzymes involved in the fifth (last) step in the biosynthesis of spermidine from arginine and methionine which includes; spermidine synthase (), spermine synthase () and putrescine N-methyltransferase () . The Thermotoga maritima spermidine synthase monomer consists of two domains: an N-terminal domain composed of six beta-strands, and a Rossmann-like C- terminal domain . The larger C-terminal catalytic core domain consists of a seven-stranded beta-sheet flanked by nine alpha helices. This domain resembles a topology observed in a number of nucleotide and dinucleotide-binding enzymes, and in S-adenosyl-L-methionine (AdoMet)- dependent methyltransferase (MTases) . ; GO: 0003824 catalytic activity.
