Exodeoxyribonuclease I <p>This entry represents exodeoxyribonuclease I. It functions as a DNA deoxyribophosphodiesterase that releases deoxyribose-phosphate moieties following the cleavage DNA at an apurinic/apyrimidinic (AP) site by either an AP endonuclease AP lyase; exonucleolytic cleavage in the 3'- to 5'-direction yields nucleoside 5'-phosphates [<cite idref="PUB00020975"/>].</p>
