Agmatine deiminase

In enzymology, an agmatine deiminase (EC3.5.3.12) is an enzyme that catalyzes the chemical reaction

Thus, the two substrates of this enzyme are agmatine and H₂O, whereas its two products are N-carbamoylputrescine and NH₃.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amidines. The systematic name of this enzyme class is agmatine iminohydrolase. This enzyme is also called agmatine amidinohydrolase. This enzyme participates in urea cycle and metabolism of amino groups.
