IntEnz Enzyme Nomenclature


Accepted name:
agmatine deiminase
Other name:
agmatine amidinohydrolase
Systematic name:
agmatine iminohydrolase



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