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       Rule:MF_00528}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-
