Enzyme Information

2.7.7.7	DNA-directed DNA polymerase. based on mapping to UniProt A1Z651 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.
2.7.7.49	RNA-directed DNA polymerase. based on mapping to UniProt A1Z651 Deoxynucleoside triphosphate + DNA(n) = diphosphate + DNA(n+1). -!- Catalyzes RNA-template-directed extension of the 3'-end of a DNA strand by one deoxynucleotide at a time. -!- Cannot initiate a chain de novo. -!- Requires a RNA or DNA primer. -!- DNA can also serve as template. -!- See also EC 2.7.7.7.
3.1.26.4	Ribonuclease H. based on mapping to UniProt A1Z651 Endonucleolytic cleavage to 5'-phosphomonoester. -!- Acts on RNA-DNA hybrids.
