Studies on Leukocyte Phosphatases. III. Inhibition of Leukocyte Acid Phosphatase by Zinc

[摘要] Whereas the activity of leukocyte alkaline phosphatase is stimulated by Zn2+, it inhibits acid phosphatase activity. The degree of inhibition of acid phosphatase depends on the pH of the medium, being greater as the pH approaches neutrality. This inhibition may be at least partially reversed by the addition of amino acids, which suggests that interactions of Zn2+ and amino acids may play an important role in regulating the overall phosphatase activity of the leukocyte.
