Function
function
Inactive precursor of the viral replicase, which is activated by cleavages carried out by the viral protease nsP2.
Catalytic activity
- 4-O-(ADP-D-ribosyl)-L-aspartyl-[protein] + H2O = ADP-D-ribose + H+ + L-aspartyl-[protein]This reaction proceeds in the forward direction.
- 5-O-(ADP-D-ribosyl)-L-glutamyl-[protein] + H2O = ADP-D-ribose + H+ + L-glutamyl-[protein]This reaction proceeds in the forward direction.
- GTP + S-adenosyl-L-methionine = N7-methyl-GTP + S-adenosyl-L-homocysteine
- L-histidyl-[protein] + N7-methyl-GTP = diphosphate + N(tele)-(N7-methylguanosine 5'-phospho)-L-histidyl-[protein]This reaction proceeds in the forward direction.
- a 5'-end diphospho-(purine-ribonucleoside) in mRNA + H+ + N(tele)-(N7-methylguanosine 5'-phospho)-L-histidyl-[protein] = a 5'-end (N7-methyl 5'-triphosphoguanosine)-(purine-ribonucleoside) in mRNA + L-histidyl-[protein]
