Chain : A, B
UniProt : Q96662 (POLG_BVDVC)
Reaction : 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.
Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
NTP + H(2)O = NDP + phosphate.
ATP + H(2)O = ADP + phosphate.
