CC   -!- FUNCTION: Has nucleotide phosphatase activity towards ATP, GTP, CTP,
CC       TTP and UTP. May hydrolyze nucleoside diphosphates with lower
CC       efficiency. {ECO:0000255|HAMAP-Rule:MF_00796}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + H2O = a ribonucleoside 5'-
CC         diphosphate + H(+) + phosphate; Xref=Rhea:RHEA:23680,

CC         ChEBI:CHEBI:57930, ChEBI:CHEBI:61557; EC=3.6.1.15;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00796};
CC   -!- SIMILARITY: Belongs to the THEP1 NTPase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00796}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAM06769.1; Type=Erroneous initiation; Evidence={ECO:0000305};
