Function and Biology Details
Reactions catalysed:
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
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.
Selective cleavage of Tyr-|-Gly bond in picornavirus polyprotein.
NTP + H(2)O = NDP + phosphate
