Accepted name: deoxynucleotide 3'-phosphatase

Reaction: A 2'-deoxyribonucleoside 3'-phosphate + H2O = a 2'-deoxyribonucleoside + phosphate

Other name(s): 3'-deoxynucleotidase; 3'-deoxyribonucleotidase

Systematic name: 2'-deoxyribonucleotide 3'-phosphohydrolase

Comments: Also catalyses the selective removal of 3'-phosphate groups from DNA and oligodeoxyribonucleotides. Induced in Escherichia coli by T-even phages.
