CC   -!- FUNCTION: Nucleoside triphosphate pyrophosphatase that hydrolyzes 7-
CC       methyl-GTP (m(7)GTP). May have a dual role in cell division arrest and
CC       in preventing the incorporation of modified nucleotides into cellular
CC       nucleic acids. {ECO:0000255|HAMAP-Rule:MF_00528}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + N(7)-methyl-GTP = diphosphate + H(+) + N(7)-methyl-GMP;

CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00528};
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00528}.
CC   -!- SIMILARITY: Belongs to the Maf family. YceF subfamily.
