ENZYME entry: EC 2.5.1.23

PURL: https://purl.expasy.org/enzyme/EC/2.5.1.23
Accepted Name
sym-norspermidine synthase
Reaction catalysed
S-adenosyl 3-(methylsulfanyl)propylamine + propane-1,3-diamine = norspermidine + S-methyl-5'-thioadenosine + H(+)
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-(methylsulfanyl)propylamine to putrescine, sym-norspermidine and spermidine with lower efficiency. cf. EC 2.5.1.16 and EC 2.5.1.22.
