Function and Biology Details

Reactions catalysed:
[RNA(n) + a ribonucleoside 5'-triphosphate = RNA(n+1) + diphosphate.]
[Selective cleavage of Gln-|-Gly bond in the poliovirus polyprotein. Inother picornavirus reactions Glu may be substituted for Gln, and Ser orThr for Gly.]
[Selective cleavage of Tyr-|-Gly bond in the picornavirus polyprotein.]
[a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-diphosphate+ phosphate + H(+).]
