Agmatine + H2O <=> putrescine + urea

As it hydrolyzes a guanidino group within agmatine and also contains signature amino acid residues that act as ligand binding sites for the potential Mn(++) cofactor, agmatinase is classified as a member of the arginase superfamily (Morris, 2003).

鉴于其可在精氨酸胍基团内进行水解，且含有作为潜在Mn(++)辅因子配体结合位的特征氨基酸残基，精氨酸酶被归类为精氨酸酶超家族的成员（Morris, 2003）。
