pyrophosphatase

 [pi″ro-fos´fah-tās]
any enzyme that catalyzes the hydrolysis of central pyrophosphate linkages.

py·ro·phos·pha·tase

(pī'rō-fos'fă-tās),
Any enzyme catalyzing the hydrolysis of a pyrophosphate bond between two phosphoric groups, leaving one on each of the two fragments, for example, inorganic pyrophosphatase, NAD+ p. (cleaves NAD, etc., to mononucleotides), ATP pyrophosphatase (cleaves inorganic pyrophosphate from ATP, leaving AMP).
