In enzymology, an adenine deaminase (EC 3.5.4.2) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are adenine and H2O, whereas its two products are hypoxanthine 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 adenine aminohydrolase. Other names in common use include adenase, adenine aminase, and ADase. This enzyme participates in purine metabolism.
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2ICS.

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 converts into IMP and the byproduct ammonia. IMP converts to S-AMP (adenylosuccinate), which then converts 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.
