In enzymology, an adenosine-tetraphosphatase (EC 3.6.1.14) is an enzyme that catalyzes the chemical reaction
- adenosine 5'-tetraphosphate + H2O ATP + phosphate
Thus, the two substrates of this enzyme are adenosine 5'-tetraphosphate and H2O, whereas its two products are ATP and phosphate.
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 adenosine-tetraphosphate phosphohydrolase. This enzyme participates in purine metabolism.
Structural studies
[edit]As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2V7Q.
