pyrophosphatase[‚pī·rō′fä·sfə‚tās] (biochemistry) An enzyme catalyzing hydrolysis of esters containing two or more molecules of phosphoric acid to form a simpler phosphate ester. pyrophosphatase
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). See also: flavin adenine dinucleotide.
