In enzymology, a bis(5'-adenosyl)-triphosphatase (EC 3.6.1.29) is an enzyme that catalyzes the chemical reaction

P1,P3-bis(5'-adenosyl) triphosphate + H2O ADP + AMP

Thus, the two substrates of this enzyme are P1,P3-bis(5'-adenosyl) triphosphate and H2O, whereas its two products are ADP and AMP.

This enzyme belongs to the family of hydrolases, specifically those acting on acid anhydrides in phosphorus-containing anhydrides. The systematic name of this enzyme class is P1,P3-bis(5'-adenosyl)-triphosphate adenylohydrolase. Other names in common use include dinucleosidetriphosphatase, diadenosine 5,5-P1,P3-triphosphatase, and 1-P,3-P-bis(5'-adenosyl)-triphosphate adenylohydrolase. This enzyme participates metabolic pathways involved in purine metabolism, and may have a role in the development of small cell lung cancer, and non-small cell lung cancer.

Structural studies

As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes 1FHI, 2FHI, 4FIT, 5FIT, and 6FIT.

<span class="mw-page-title-main">Pyrophosphate</span> Class of chemical compounds

In chemistry, pyrophosphates are phosphorus oxyanions that contain two phosphorus atoms in a P–O–P linkage. A number of pyrophosphate salts exist, such as disodium pyrophosphate (Na2H2P2O7) and tetrasodium pyrophosphate (Na4P2O7), among others. Often pyrophosphates are called diphosphates. The parent pyrophosphates are derived from partial or complete neutralization of pyrophosphoric acid. The pyrophosphate bond is also sometimes referred to as a phosphoanhydride bond, a naming convention which emphasizes the loss of water that occurs when two phosphates form a new P–O–P bond, and which mirrors the nomenclature for anhydrides of carboxylic acids. Pyrophosphates are found in ATP and other nucleotide triphosphates, which are important in biochemistry. The term pyrophosphate is also the name of esters formed by the condensation of a phosphorylated biological compound with inorganic phosphate, as for dimethylallyl pyrophosphate. This bond is also referred to as a high-energy phosphate bond.
