In enzymology, an ATP deaminase (EC 3.5.4.18) is an enzyme that catalyzes the chemical reaction

ATP + H2O ITP + NH3

Thus, the two substrates of this enzyme are ATP and H2O, whereas its two products are ITP and NH3.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in cyclic amidines. The systematic name of this enzyme class is ATP aminohydrolase. This enzyme is also called adenosine triphosphate deaminase.

<span class="mw-page-title-main">Purine nucleotide cycle</span>

The Purine Nucleotide Cycle is a metabolic pathway in protein metabolism requiring the amino acids aspartate and glutamate. The cycle is used to regulate the levels of adenine nucleotides, in which ammonia and fumarate are generated. AMP coverts into IMP and the byproduct ammonia. IMP converts to S-AMP (adenylosuccinate), which then coverts to AMP and the byproduct fumarate. The fumarate goes on to produce ATP (energy) via oxidative phosphorylation as it enters the Krebs cycle and then the electron transport chain. Lowenstein first described this pathway and outlined its importance in processes including amino acid catabolism and regulation of flux through glycolysis and the Krebs cycle.
