CC -!- FUNCTION: Second step of mRNA capping. Transfer of the GMP moiety of
CC GTP to the 5'-end of RNA via an enzyme-GMP covalent reaction
CC intermediate. {ECO:0000256|PIRNR:PIRNR036959}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end diphospho-ribonucleoside in mRNA + GTP + H(+) = a 5'-
CC end (5'-triphosphoguanosine)-(ribonucleoside) in mRNA + diphosphate;
