Enzyme Information
| 2.7.7.7 |
DNA-directed DNA polymerase.
based on mapping to UniProt P19821
Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1).
-!- Catalyzes 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.
