Examples include:
- Inorganic pyrophosphatase, which acts upon the free pyrophosphate ion
- Tobacco acid pyrophosphatase, which catalyses the hydrolysis of a phosphoric ester
- Various organic pyrophosphatases, which act upon organic molecules with the pyrophosphate group (but excluding triphosphatases that act on the final bond):
