ENZYME entry: EC

Accepted Name
N(1)-aminopropylagmatine synthase.
Alternative Name(s)
Agmatine aminopropyltransferase.
Agmatine/cadaverine aminopropyl transferase.
Triamine/agmatine aminopropyltransferase.
Reaction catalysed
S-adenosylmethioninamine + agmatine <=> S-methyl-5'-thioadenosine + N(1)-(3-aminopropyl)agmatine
  • The enzyme is involved in the biosynthesis of spermidine from agmatine in some archaea and bacteria.
  • The enzyme from the Gram-negative bacterium Thermus thermophilus accepts agmatine, spermidine and norspermidine with similar catalytic efficiency.
  • The enzymes from the archaea Pyrococcus furiosus and Thermococcus kodakarensis prefer agmatine, but can utilize cadaverine, putrescine and propane-1,3-diamine with much lower catalytic efficiency.
