Properties and Distribution of Inorganic Pyrophosphatase in Rabbit Dental Pulp

Abstract
Some properties and the intracellular distribution of inorganic pyrophosphatase in rabbit dental pulp were determined. This enzyme was sensitive to Mg2+, and not inhibited by imidazol and CN- which are inhibitors of alkaline phosphatase. Inorganic pyrophosphatase was found predominantly in the supernatant fraction.
