CC   -!- FUNCTION: Nucleoside triphosphate pyrophosphatase that hydrolyzes dTTP
CC       and UTP. May have a dual role in cell division arrest and in preventing
CC       the incorporation of modified nucleotides into cellular nucleic acids.
CC       {ECO:0000255|HAMAP-Rule:MF_00528}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=dTTP + H2O = diphosphate + dTMP + H(+); Xref=Rhea:RHEA:28534,
