Enzyme Information

2.7.7.-	Nucleotidyltransferases. based on mapping to UniProt P35956
3.4.23.-	Aspartic endopeptidases. based on mapping to UniProt P35956
3.6.1.23	dUTP diphosphatase. based on mapping to UniProt P35956 dUTP + H(2)O = dUMP + diphosphate.
3.1.13.2	Exoribonuclease H. based on mapping to UniProt P35956 3'-end directed exonucleolytic cleavage of viral RNA-DNA hybrid. -!- This is a secondary reaction to the RNA 5'-end directed cleavage 13-19 nucleotides from the RNA end performed by EC 3.1.26.13.
2.7.7.49	RNA-directed DNA polymerase. based on mapping to UniProt P35956 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 P35956 Endonucleolytic cleavage to 5'-phosphomonoester. -!- Acts on RNA-DNA hybrids.
3.1.-.-	Acting on ester bonds. based on mapping to UniProt P35956
2.7.7.7	DNA-directed DNA polymerase. based on mapping to UniProt P35956 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.
