Title: Phosphorylation as a method of regulating the activity of yeast inorganic pyrophosphatase. I. Activation of inorganic pyrophosphatase under the action of ATP
Abstract: ATP activates in a noncompetitive manner the hydrolysis of magnesium pyrophosphate catalyzed by baker's yeast inorganic pyrophosphatase. On the other hand, ATP causes a fall in the amount of pyrophosphate bound with enzyme that is formed by synthesis from phosphate, which confirms the fact of an increase in the catalytic rate constant of the enzymatic hydrolysis of pyrophosphate. The reason for the activation of the inorganic pyrophosphatase is the phosphorylation of its regulatory center under the action of ATP with the inclusion of the ..gamma..-phosphate group of the ATP in the protein.
