Function and Biology Details

Reactions catalysed:
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1)
Leu is conserved at position P1 for all four cleavage sites. Alanine is found at position P1' of the NS4A-NS4B cleavage site, whereas serine is found at position P1' of the NS3-NS4A, NS4B-NS5A and NS5A-NS5B cleavage sites
NTP + H(2)O = NDP + phosphate
ATP + H(2)O = ADP + phosphate
(1a) RNA = an (RNA fragment)-3'-nucleoside-2',3'-cyclophosphate + a 5'-hydroxy-ribonucleotide-3'-(RNA fragment)
