| 2.5.1.22 | in complex with 5'-methylthioadenosine and spermidine and with 5'-methylthioadenosine and spermine. Enzyme is a dimer of two identical subunits. Each monomer has three domains, a C-terminal domain, which contains the active site and is similar in structure to spermidine synthase, a central domain made up of four beta-strands, and an N-terminal domain with remarkable structural similarity to S-adenosylmethionine decarboxylase |

| 2.5.1.22 | Purified SpmSyn is crystallized as ternary complex in the presence of spermidine and 5'-methylthioadenosine or spermidine and 5'-methylthioadenosine using the hanging drop vapor diffusion method. The SpmSyn-5'-methylthioadenosine-spermidine complex is crystallized in 12% polyethylene glycol and 0.1 M MES (pH 6.5). The SpmSyn-5'-methylthioadenosine-spermine complex is crystallized in 18% polyethylene glycol, 0.1 M NaCl, and 0.1 M BisTris (pH 6.5). Crystals are soaked in the corresponding mother liquor supplemented with 20% glycerol as cryoprotectant before freezing in liquid nitrogen. |
