ENZYME entry: EC 2.5.1.23

Accepted Name
Sym-norspermidine synthase.
Reaction catalysed
S-adenosyl 3-(methylthio)propylamine + propane-1,3-diamine <=> S-methyl-5'-thioadenosine + bis(3-aminopropyl)amine
Comment(s)
  • The enzyme has been originally characterized from the protist Euglena gracilis.
  • The enzyme from the archaeon Sulfolobus solfataricus can transfer the propylamine moiety from S-adenosyl 3-(methylthio)propylamine to putrescine, sym-norspermidine and spermidine with lower efficiency.
  • Cf. EC 2.5.1.16 and EC 2.5.1.22.
