In enzymology a sym-norspermidine synthase (EC 2.5.1.23) is an enzyme that catalyzes the chemical reactionS-adenosylmethioninamine + propane-13-diamine 5′-methylthioadenosine + bis(3-aminopropyl)amineThus the two substrates of this enzyme are S-adenosylmethioninamine and propane-13-diamine whereas its two products are 5′-methylthioadenosine and bis(3-aminopropyl)amine.This enzyme belongs to the family of transferases specifically those transferring aryl or alkyl groups other than methyl groups.
