Function and Biology Details

Reactions catalysed: 
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
Hydrolysis of four peptide bonds in the viral precursor polyprotein, commonly with Asp or Glu in the P6 position, Cys or Thr in P1 and Ser or Ala in P1'.
NTP + H(2)O = NDP + phosphate
ATP + H(2)O = ADP + phosphate
