Enzyme Information

2.7.7.48
RNA-directed RNA polymerase.
based on mapping to UniProt P0C6Y3
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
-!- Catalyzes RNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. -!- Can initiate a chain de novo. -!- See also EC 2.7.7.6.
3.1.13.-
Exoribonucleases producing 5'-phosphomonoesters.
based on mapping to UniProt P0C6Y3
2.1.1.-
Methyltransferases.
based on mapping to UniProt P0C6Y3
3.1.-.-
Acting on ester bonds.
based on mapping to UniProt P0C6Y3
3.6.4.12
DNA helicase.
based on mapping to UniProt P0C6Y3
ATP + H(2)O = ADP + phosphate.
-!- DNA helicases utilize the energy from ATP hydrolysis to unwind double-stranded DNA. -!- Some of them unwind duplex DNA with a 3' to 5' polarity (1,3,5,8), other show 5' to 3' polarity (10,11,12,13) or unwind DNA in both directions (14,15). -!- Some helicases unwind DNA as well as RNA (4,9). -!- May be identical with EC 3.6.4.13 (RNA helicase).
