Chain A,B,C,D   (SPEE_THEMA | Q9WZC2)
molecular function
    GO:0043919    agmatine aminopropyltransferase activity    Catalysis of the reaction: agmatine + S-adenosylmethioninamine = N1-aminopropylagmatine + 5'-methylthioadenosine.
    GO:0043918    cadaverine aminopropyltransferase activity    Catalysis of the reaction: S-adenosylmethioninamine + cadaverine = 5'-methylthioadenosine + N-(3-aminopropyl)cadaverine.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0004766    spermidine synthase activity    Catalysis of the reaction: S-adenosylmethioninamine + putrescine = 5'-methylthioadenosine + spermidine.
    GO:0050314    sym-norspermidine synthase activity    Catalysis of the reaction: 1,3-diaminopropane + S-adenosylmethioninamine = S-methyl-5'-thioadenosine + bis(3-aminopropyl)amine + H(+).
    GO:0010487    thermospermine synthase activity    Catalysis of the reaction: S-adenosyl-L-methioninamine + spermidine = S-methyl-5'-thioadenosine + thermospermine + H+.
    GO:0016740    transferase activity    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.
biological process
    GO:0006596    polyamine biosynthetic process    The chemical reactions and pathways resulting in the formation of polyamines, any organic compound containing two or more amino groups.
    GO:0008295    spermidine biosynthetic process    The chemical reactions and pathways resulting in the formation of spermidine, N-(3-aminopropyl)-1,4-diaminobutane.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
