The enzyme 3′(2′),5′-bisphosphate nucleotidase (EC 3.1.3.7) catalyzes the reaction

adenosine 3′,5′-bisphosphate + H₂O ${\displaystyle \rightleftharpoons }$ AMP + phosphate

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is adenosine-3′(2′),5′-bisphosphate 3′(2′)-phosphohydrolase. Other names in common use include phosphoadenylate 3′-nucleotidase, 3′-phosphoadenylylsulfate 3′-phosphatase, 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.
