CC -!- FUNCTION: Decapping scavenger enzyme that catalyzes the cleavage of a
CC residual cap structure following the degradation of mRNAs by the 3'->5'
CC exosome-mediated mRNA decay pathway. {ECO:0000256|PIRNR:PIRNR028973}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside
CC in mRNA + H2O = a 5'-end diphospho-ribonucleoside in mRNA + 2 H(+) +
CC N(7)-methyl-GMP; Xref=Rhea:RHEA:65388, Rhea:RHEA-COMP:17165,
CC Rhea:RHEA-COMP:17167, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
