The plant enzyme also catalyses the reactions of EC 220.127.116.11 (ornithine carbamoyltransferase), EC 18.104.22.168 (putrescine carbamoyltransferase) and EC 22.214.171.124 (carbamate kinase), thus functioning as a putrescine synthase, converting agmatine and ornithine into putrescine and citrulline, respectively.
