EC 2.7.7.7     
Accepted name: DNA-directed DNA polymerase
Reaction: a 2′-deoxyribonucleoside 5′-triphosphate + DNAn = diphosphate + DNAn+1
Other name(s): DNA polymerase I; DNA polymerase II; DNA polymerase III; DNA polymerase α; DNA polymerase β; DNA polymerase γ; DNA nucleotidyltransferase (DNA-directed); deoxyribonucleate nucleotidyltransferase; deoxynucleate polymerase; deoxyribonucleic acid duplicase; deoxyribonucleic acid polymerase; deoxyribonucleic duplicase; deoxyribonucleic polymerase; deoxyribonucleic polymerase I; DNA duplicase; DNA nucleotidyltransferase; DNA polymerase; DNA replicase; DNA-dependent DNA polymerase; duplicase; Klenow fragment; sequenase; Taq DNA polymerase; Taq Pol I; Tca DNA polymerase
Systematic name: 2′-deoxyribonucleoside-5′-triphosphate:DNA deoxynucleotidyltransferase (DNA-directed)
Comments: Catalyses DNA-template-directed extension of the 3′- end of a DNA strand by one nucleotide at a time. Cannot initiate a chain de novo. Requires a primer, which may be DNA or RNA. See also EC 2.7.7.49 RNA-directed DNA polymerase.
