Enzyme Information

N(4)-bis(aminopropyl)spermidine synthase.
based on mapping to UniProt Q5JIZ3
2 S-adenosyl 3-(methylthio)propylamine + spermidine = 2 S-methyl- 5'-thioadenosine + N(4)-bis(aminopropyl)spermidine.
-!- The enzyme, characterized from the thermophilic archaeon Thermococcus kodakarensis, synthesizes the branched-chain polyamine N(4)- bis(aminopropyl)spermidine, which is required for cell growth at high-temperature. -!- When spermine is used as substrate, the enzyme forms N(4)- aminopropylspermine.
