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 ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:37568, ChEBI:CHEBI:63528; EC=3.6.1.9;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00528};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + UTP = diphosphate + H(+) + UMP; Xref=Rhea:RHEA:29395,

CC ChEBI:CHEBI:46398, ChEBI:CHEBI:57865; EC=3.6.1.9;
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 ECO:0000305}.
CC -!- SIMILARITY: Belongs to the Maf family. YhdE subfamily.
