The enzyme polynucleotide 3â²-phosphatase (EC 3.1.3.32) catalyzes the reaction
This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is polynucleotide 3'-phosphohydrolase. Other names in common use include 2â²(3â²)-polynucleotidase, DNA 3â²-phosphatase, deoxyribonucleate 3â²-phosphatase, and 5â²-polynucleotidekinase 3â²-phosphatase.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
