Nucleoside-Triphosphatase

NTPase; Nucleoside Triphosphatase; Nucleoside Triphosphate Phosphohydrolase; Nucleoside Triphosphate Phosphohydrolase I; Nucleoside Triphosphate Phosphohydrolase II; Nucleosidetriphosphatase; Phosphohydrolase, Nucleoside Triphosphate
An enzyme which catalyzes the hydrolysis of nucleoside triphosphates to nucleoside diphosphates. It may also catalyze the hydrolysis of nucleotide triphosphates, diphosphates, thiamine diphosphates and FAD. The nucleoside triphosphate phosphohydrolases I and II are subtypes of the enzyme which are found mostly in viruses.
