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 = L-aspartyl-[protein] + ADP-D-ribose + H+This reaction proceeds in the forward direction.
- 5-O-(ADP-D-ribosyl)-L-glutamyl-[protein] + H2O = L-glutamyl-[protein] + ADP-D-ribose + H+This reaction proceeds in the forward direction.
- GTP + S-adenosyl-L-methionine = N7-methyl-GTP + S-adenosyl-L-homocysteine
- N7-methyl-GTP + L-histidyl-[protein] = N(tele)-(N7-methylguanosine 5'-phospho)-L-histidyl-[protein] + diphosphateThis reaction proceeds in the forward direction.
- N(tele)-(N7-methylguanosine 5'-phospho)-L-histidyl-[protein] + a 5'-end diphospho-(purine-ribonucleoside) in mRNA + H+ = a 5'-end (N7-methyl 5'-triphosphoguanosine)-(purine-ribonucleoside) in mRNA + L-histidyl-[protein]

Interaction
Subunit
Interacts with RNA-directed RNA polymerase nsP4. Interacts with mRNA-capping enzyme nsP1. Interacts with KPNA1/karyopherin-alpha1; this interaction probably allows the active transport of protease nsP2 into the host nucleus.
