Spermidine synthase tetramerisation domain

This domain represents the N-terminal tetramerization domain from spermidine synthase. (from Pfam)

spermidine synthase

spermidine synthase catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine; belongs to the class I SAM-dependent methyltransferase superfamily

fused MFS/spermidine synthase

Proteins of this family are fusion of a N-terminal MFS (Major Facilitator Superfamily) transporter domain and a C-terminal spermidine synthase (SpdSyn)-like domain. The encoding genes usually near the genes encoding S-adenosylmethionine decarboxylase (AdoMetDC) on many bacterial genomes. It has been shown in Shewanella oneidensis that the fused protein aminopropylates a substrate other than putrescine, and has a role outside of polyamine biosynthesis.
