In enzymology, an agmatine deiminase (EC 3.5.3.12) is an enzyme that catalyzes the chemical reaction

agmatine + H2O N-carbamoylputrescine + NH3

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.

Structural studies

As of late 2007, 4 structures have been solved for this class of enzymes, with PDB accession codes 1VKP, 2EWO, 2JER, and 2Q3U.

Putrescine is an organic compound with the formula (CH2)4(NH2)2. It is a colorless solid that melts near room temperature. It is classified as a diamine. Together with cadaverine, it is largely responsible for the foul odor of putrefying flesh, but also contributes to other unpleasant odors.

Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses. It functions as an intracellular free radical scavenger to protect DNA from free radical attack. Spermine is the chemical primarily responsible for the characteristic odor of semen.
