Enzyme Information
| 2.7.7.- | Nucleotidyltransferases. based on mapping to UniProt Q8JUX6 | 
| 3.6.4.13 | RNA helicase. based on mapping to UniProt Q8JUX6 ATP + H(2)O = ADP + phosphate. -!- RNA helicases utilize the energy from ATP hydrolysis to unwind RNA. -!- Some of them unwind RNA with a 3' to 5' polarity, other show 5' to 3' polarity. -!- Some helicases unwind DNA as well as RNA. -!- May be identical with EC 3.6.4.12 (DNA helicase). | 
| 3.6.1.15 | Nucleoside-triphosphate phosphatase. based on mapping to UniProt Q8JUX6 NTP + H(2)O = NDP + phosphate. -!- The enzyme is found in eukaryotes and thermophilic bacteria, but appears to be absent from mesophilic bacteria. -!- Also hydrolyzes nucleoside diphosphates, thiamine diphosphate and FAD. -!- The enzyme from the plant Pisum sativum (garden pea) is regulated by calmodulin. | 
| 2.1.1.- | Methyltransferases. based on mapping to UniProt Q8JUX6 | 
| 2.7.7.19 | Polynucleotide adenylyltransferase. based on mapping to UniProt Q8JUX6 ATP + RNA(n) = diphosphate + RNA(n+1). -!- Also acts slowly with CTP. -!- Catalyzes template-independent extension of the 3'-end of a DNA strand by one nucleotide at a time. -!- Cannot initiate a chain de novo. -!- The primer, depending on the source of the enzyme, may be an RNA or DNA fragment or oligo(A) bearing a 3'-OH terminal group. -!- See also EC 2.7.7.6. | 
| 2.7.7.48 | RNA-directed RNA polymerase. based on mapping to UniProt Q8JUX6 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. | 
| 3.1.3.33 | Polynucleotide 5'-phosphatase. based on mapping to UniProt Q8JUX6 A 5'-phosphopolynucleotide + H(2)O = a polynucleotide + phosphate. -!- Does not act on nucleoside monophosphates. -!- Induced in Escherichia coli by T-even phages. | 
| 3.1.3.84 | ADP-ribose 1''-phosphate phosphatase. based on mapping to UniProt Q8JUX6 ADP-D-ribose 1''-phosphate + H(2)O = ADP-D-ribose + phosphate. -!- The enzyme is highly specific for ADP-D-ribose 1''-phosphate. -!- Involved together with EC 3.1.4.37 in the breakdown of adenosine diphosphate ribose 1'',2''-cyclic phosphate (Appr>p), a by-product of tRNA splicing. -!- Formerly EC 3.1.3.n2. | 
| 3.4.22.- | Cysteine endopeptidases. based on mapping to UniProt Q8JUX6 |
