Polynucleotide 3'-phosphatase
- Polynucleotide 3'-phosphatase
In enzymology, a polynucleotide 3'-phosphatase (EC number|3.1.3.32) is an enzyme that catalyzes the chemical reaction
:a 3'-phosphopolynucleotide + H2O a polynucleotide + phosphate
Thus, the two substrates of this enzyme are 3'-phosphopolynucleotide and H2O, whereas its two products are polynucleotide 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 polynucleotide 3'-phosphohydrolase. Other names in common use include 2'(3')-polynucleotidase, DNA 3'-phosphatase, deoxyribonucleate 3'-phosphatase, and 5'-polynucleotidekinase 3'-phosphatase.
tructural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link|1UJX and PDB link|2BRF.
