Thus, the two substrates of this enzyme are adenosine 3',5'-bisphosphate and H2O, whereas its two products are adenosine 5'-phosphate and phosphate.
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is adenosine-3'(2'),5'-bisphosphate 3'(2')-phosphohydrolase. Other names in common use include phosphoadenylate 3'-nucleotidase, 3'-phosphoadenylylsulfate 3'-phosphatase, phosphoadenylate 3'-nucleotidase, and 3'(2'),5'-bisphosphonucleoside 3'(2')-phosphohydrolase. This enzyme participates in sulfur metabolism.
Structural studies
As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1JP4, 1K9Y, 1K9Z, 1KA0, 1KA1, and 1QGX.
