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.
Autocatalytically cleaves itself from the polyprotein of the foot-and-mouth disease virus by hydrolysis of a Lys-|-Gly bond, but then cleaves host cell initiation factor eIF-4G at bonds -Gly-|-Arg- and -Lys-|-Arg-.
NTP + H(2)O = NDP + phosphate
