Reaction: A 3'-phosphopolynucleotide + H2O = a polynucleotide + phosphate
Other name(s): 2'(3')-polynucleotidase; DNA 3'-phosphatase; deoxyribonucleate 3'-phosphatase; 5'-polynucleotidekinase 3'-phosphatase
Systematic name: polynucleotide 3'-phosphohydrolase
Comments: Also hydrolyses nucleoside 2'-, 3'- and 5'-monophosphates, but only 2'- and 3'-phosphopolynucleotides.
