Function and Biology Details

Reactions catalysed:
DNA(n) + a 2'-deoxyribonucleoside 5'-triphosphate = DNA(n+1) +diphosphate.
2'-deoxyribonucleotide-(2'-deoxyribose 5'-phosphate)-2'-deoxyribonucleotide-DNA = a 3'-end 2'-deoxyribonucleotide-(2,3-dehydro-2,3-deoxyribose 5'-phosphate)-DNA + a 5'-end 5'-phospho-2'-deoxyribonucleoside-DNA + H(+).
