Adenosine-tetraphosphatase

Adenosine-tetraphosphatase

In enzymology, an adenosine-tetraphosphatase (EC number|3.6.1.14) is an enzyme that catalyzes the chemical reaction

:adenosine 5'-tetraphosphate + H2O ightleftharpoons 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.

tructural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB link|2V7Q.
