CC -!- FUNCTION: Nucleoside triphosphate pyrophosphatase. May have a dual role
CC in cell division arrest and in preventing the incorporation of modified
CC nucleotides into cellular nucleic acids. {ECO:0000255|HAMAP-

CC Evidence={ECO:0000255|HAMAP-Rule:MF_00528};
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. {ECO:0000255|HAMAP-
