Enzyme Information
| 3.6.1.15 | Nucleoside-triphosphate phosphatase. based on mapping to UniProt P03313 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. | 
| 2.7.7.48 | RNA-directed RNA polymerase. based on mapping to UniProt P03313 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. | 
| 3.4.22.28 | Picornain 3C. based on mapping to UniProt P03313 Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. In other picornavirus reactions Glu may be substituted for Gln, and Ser or Thr for Gly. -!- From entero-, rhino-, aphto- and cardioviruses. -!- Larger than the homologous virus picornain 2A. -!- Belongs to peptidase family C3. | 
| 3.4.22.29 | Picornain 2A. based on mapping to UniProt P03313 Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein. -!- From entero- and rhinoviruses. -!- Smaller than the homologous virus picornain 3C. -!- Belongs to peptidase family C3. |
