PF17284Spermidine synthase tetramerisation domain (Spermine_synt_N)Spermidine synthase tetramerisation domainThis domain represents the N-terminal tetramerization domain from spermidine synthase.Domain
PF01564Spermine/spermidine synthase domain (Spermine_synth)Spermine/spermidine synthase domainSpermine 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.Domain
