Spermidine synthase tetramerisation domain

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

Date:: 2024-08-14

Family Accession:: NF036419.5
Method:: HMM

Select item 4121752.

Spermine and spermidine are polyamines. This family includes spermidine synthase that catalyses the fifth (last) step in the biosynthesis of spermidine from arginine, and spermine synthase. (from Pfam)

spermidine synthase

spermidine synthase catalyzes the irreversible transfer of a propylamine group from S-adenosylmethioninamine to putrescine to form spermidine

polyamine aminopropyltransferase

Gene:: speE

Family Accession:: NF002010.0
Method:: HMM

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.

spermidine synthase

the SpeE subunit of spermidine synthase catalysesthe reaction (putrescine + S-adenosylmethioninamine = spermidine + 5'-methylthioadenosine) and is involved in polyamine biosynthesis and in the biosynthesis of spermidine from arganine. The region between residues 77 and 120 of the seed alignment is thought to be involved in binding to decarboxylated SAM.
