Abstract
The presence of triphosphatase, diphosphatase and nucleotidase is reported in the scorpion muscle. Each phosphatase is shown to be substrate specific and to exist in three different ionic species with specific pH optima. With change in substrate from ATP to AMP, there is a gradual shift in the pH optima of the different fractions of the phosphatases towards the acid side. The possibility of differential intracellular localization of these ionic species of each phosphatase is suggested.
