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,

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. YhdE subfamily.
