By M. Kunitz. Journal of General Physiology 35(3), 423–450 (20 January 1952).

Verified locator: abstract, specific hydrolysis of inorganic pyrophosphate, metal-ion activation and dependence of reaction rate on conditions. Primary study isolates the crystalline enzyme; it does not report the mechanism of every cellular pyrophosphatase.
