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.
  • ADP-alpha-D-ribose 1''-phosphate + H2O = ADP-D-ribose + phosphate
    This reaction proceeds in the forward direction.
    EC:3.1.3.84 (UniProtKB | ENZYME | Rhea)
  • ATP + H2O = ADP + H+ + phosphate
    EC:3.6.4.13 (UniProtKB | ENZYME | Rhea)
  • ATP + RNA(n) = diphosphate + RNA(n)-3'-adenine ribonucleotide
    EC:2.7.7.19 (UniProtKB | ENZYME | Rhea)
  • 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]
  • a 5'-end triphospho-ribonucleoside in mRNA + H2O = a 5'-end diphospho-ribonucleoside in mRNA + H+ + phosphate
    This reaction proceeds in the forward direction.
    EC:3.6.1.74 (UniProtKB | ENZYME | Rhea)
  • a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-diphosphate + H+ + phosphate
    EC:3.6.1.15 (UniProtKB | ENZYME | Rhea)
