- karbamoil fosfat + putrescin fosfat + N-karbamoilputrescin
Ovaj biljni enzim takođe katalizuje reakcije EC 2.1.3.3, ornitin karbamoiltransferaze, EC 2.7.2.2, karbamatne kinaze i EC 3.5.3.12, agmatinske deiminaze. On deluje kao putrescinska sintaza, koja konvertuje agmatin [(4-aminobutil)guanidin] i ornitin u putrescin i citrulin, respektivno.
