CC   -!- FUNCTION: First step of mRNA capping. Converts the 5'-triphosphate end
CC       of a nascent mRNA chain into a diphosphate end.
CC       {ECO:0000250|UniProtKB:O13297}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a 5'-end triphospho-ribonucleoside in mRNA + H2O = a 5'-end
CC         diphospho-ribonucleoside in mRNA + H(+) + phosphate;

CC         Evidence={ECO:0000250|UniProtKB:O13297};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:67005;
CC         Evidence={ECO:0000250|UniProtKB:O13297};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:O13297};
CC   -!- SUBUNIT: Heterodimer. The mRNA-capping enzyme is composed of two
CC       separate chains alpha and beta, respectively a mRNA guanylyltransferase
CC       and an mRNA 5'-triphosphate monophosphatase.
CC       {ECO:0000250|UniProtKB:O13297}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the fungal TPase family. {ECO:0000305}.
