ID 2.5.1.104 DE N(1)-aminopropylagmatine synthase. AN ACAPT. AN agmatine/cadaverine aminopropyl transferase. AN agmatine aminopropyltransferase. AN triamine/agmatine aminopropyltransferase. CA agmatine + S-adenosyl 3-(methylsulfanyl)propylamine = H(+) + N(1)- CA aminopropylagmatine + S-methyl-5'-thioadenosine. CC -!- The enzyme is involved in the biosynthesis of spermidine from CC agmatine in some archaea and bacteria. CC -!- The enzyme from the Gram-negative bacterium Thermus thermophilus CC accepts agmatine, spermidine and norspermidine with similar catalytic CC efficiency. CC -!- The enzymes from the archaea Pyrococcus furiosus and Thermococcus CC kodakarensis prefer agmatine, but can utilize cadaverine, putrescine CC and propane-1,3-diamine with much lower catalytic efficiency. cf. CC EC 2.5.1.16 and EC 2.5.1.23. DR Q8U4G1, SPEE_PYRFU ; Q5JFG9, SPEE_THEKO ; Q5SK28, SPEE_THET8 ; //
