ENZYME entry: EC 3.6.1.62

Accepted Name
5'-(N(7)-methylguanosine 5'-triphospho)-[mRNA] hydrolase
Alternative Name(s)
m(7)GpppN-mRNA hydrolase
Reaction catalysed
a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside in mRNA + H2O <=> a 5'-end phospho-ribonucleoside in mRNA + 2 H(+) + N(7)-methyl-GDP
Comment(s)
  • Decapping of mRNA is a critical step in eukaryotic mRNA turnover.
  • The enzyme is unable to cleave a free cap structure (m(7)GpppG).
  • The enzyme from Vaccinia virus is synergistically activated in the presence of Mg(2+) and Mn(2+).
  • Formerly EC 3.6.1.30.
